I am having an anoying problem generating an opentype font in fontlab:
After merging contours and generating the otf-file, my font looks fine in the preview and in fontexplorer, but when I want to use it e.g. in indesign or illustrator, some of the contours are distorted (in Textedit it works alright though). When I create outlines, all the contours look fine again.
see in the picture how it should be and how some letters are rendered.

this happened in two completely different fonts I drew.
I am using font nuke, so it does not seem to be a cache problem.

Does anyone have an idea why this happens?


Veronika Burian and Jose Scaglioné are teaching a 4-day workshop on type design and FontLab here in Portland in mid-July. Sign up this month to ensure it actually takes place! Details here:

I've been working on a mildly complex font for a client (moonlighting outside my day job).

I've never worked with using a lookupflag to ignore certain glyphs, but it seems like the perfect solution for a particular issue I encountered. So I tried to do it in FontLab. It compiled fine and I export the font, but the desired behavior is not occurring in InDesign CS5 (even when I set text with the WorldReady Composer active).

I'm wondering if I am doing something wrong, or...? Here's my process.

A) First, for the glyphs we want to be ignored, do the following in the FontLab glyph window:
- select the glyph.
- bring up the glyph properties dialog
- change the value of the OT popdown from "Unassigned" to "Mark"

I get the interesting error below when I try to compile features in an OT script font. The notable things are that the claimed number of elements is absurdly large, and the error message is claiming that a number is not equal to itself. The only features in the font are calt and maybe kern.

It seems to me that I have seen this error before, and it does mean something, but as the error message itslf is bogus, I can't recall for sure what that is. Is it related to overflow of the 64K size limit on a subtable in OpenType? That rings a bell for me....

I'm kerning a font, and the blue characters (that indicate that a glyph is part of a metrics class) in the Kerning palette of the Metrics Window distract me, so I can't as easily see where the kerning problems are.

Is there a way to turn off the blue characters?

FontLab Glyph Window Family

Is there any way to cycle quickly through weights within a family from the Glyph Window?

Basically, if I have glyph 'A' of Example Bold open and make an edit is there a command to quickly switch to Example Light in the same Glyph window to make the same edit and continue on through the family without closing the window?

FontLab Update?!!!

not sure if any of fontlab developers are around, but please please …
when are you finally going to make an update?
last one you made an update was in 2007!
the actual version is hell of a buggy one, keeps crashing all the time!
come on people, do something!

In a monospaced font, every character must take tha same amount of space, which means

"left sidebearing"+"glyph weight"+"right sidebearing" = X

Is there any way to set my value for X, instead of setting those 3 values one by one?

So a couple of years ago, I made my first font, Yagi Double. Then I wanted to hint it, got scared when I saw the amount of work involved. Now I'm ready to try again but it STILL seems too tedious, like I'm missing something. What I've read so far on the subject:

As I understand it, you come up with an array of numbers representing the location of stuff like the baseline, cap height, x-height, etc. You feed these into two different areas in Fontlab. With an inline font like this, there are twice as many of these numbers. It's a lot of hassle.

1. Does this really produce good hinting results at the end, if I could force myself to do it properly?

Has anyone experienced FontLab generating a font where the kern classes differ from the source VFB? I'm completely stumped as to why this is happening or how to get around it. I suppose I could use TTX or FontForge to replace the kern classes but I can't help wondering if this is a known bug, maybe FL needs a reinstall or perhaps I've overlooked something. Any insight would be appreciated.

Hi guys,

I recently bought Letterror's Superpolator. I've seen all the video's about it from the Robothon 2009 event, but still the program stays a bit of a mystery to me. Since there is no (known) manual for Superpolator, other than the Robothon 2009 video's, I hope there are some people out there willing to share tips and tricks. Perhaps we could even build a wiki page for it.

These are the issues I'd like to be enlightened on:

1) Importing/updating individual UFO glyphs
If you edit your masters in Fontlab and and want to update them in Superpolator, do you replace the existing master or can you update just the glyphs you editted in Fontlab?

2) Automatic update master in Superpolator

My font was exporting with a weird order so I tried to reorder first using sort glyphs then using index mode.
After saving my encoding, I exported my font and now when I type "A" another symbol comes up. This with every glyph in the font.
Any thoughts on how to fix it?

I have recently concluded my first font on Fontlab. It is a Latin base character. I have been testing out the font on programs, like Illustrator, and I have noticed a problem when I write the diacritics. Everytime I write the diacritic Illustrator automatically changes the font to Myriad. I have tried fixing the problem on Fontlab by going on the Glyph Properties window and assinging the OT to simple or ligatures, nothing works.

I have inserted an image into this post to better illustrate my problem.

Thank you.

Missing characters?

I am a rookie at fontlab - and i have run into a problem.
I made a otf with some kerning pairs. But when I try to use it in Indesign or Illustrator three characters are missing. Its really strange because I can use the font in Pages without problems.
I have no clue how this happened or how to fix it - so advice is much appreciated! (help!)

Thanks in advance :)

I have an OpenType font I am trying to convert to TrueType format with FontLab 4.5 and it just crashes when I try.

Any ideas out there?

Does anyone know how to set some parameters that restrict a font to specific sizes? In my case, I need the character to be no smaller than 12pt and no bigger than 72pt. I would like the character to change to another character for sizes smaller than 12pt or bigger than 72pt.

Is this sort of thing possible in FontLab 5 with the OpenType programming panel?


A New Tool for Illustrator folks: TypeBridge

Hi. I just wanted to comment in regards to the folks who were having difficulty with the transfer between Illustrator and TypeTool/FontLab. The way that FontLab works is logical, given that in font world there are no decimal numbers. However, for folks who are very comfortable in Illustrator, it would be nice to have a tool that automatically rounds all points (which have already been drawn) to whole points while keeping the integrity of the font.

FontLab Font window

Hi, i'm brand new here on typophile and also brand new to making fonts and fontlab and before anything let me apologize for my bad english, i'm art director and illustrator from Brazil. My question is simple: how can i add more characters on the FontLab window so i can see other characters for other languages? Right now i have the A-Z, a-z and 0-9 and a few others, but i want to make the font available for more languages. I see in fontforge a lot of characters that doesnt show on the fontlab window. Sorry if my question is silly. Anyway thanks in advance.

I just bought a new MacBook Pro and used Apple’s software to move my copy of FontLab (among other things) from my old computer to my new one. But now I have to re-enter the serial number every time I start the program.

Help regarding this problem much appriciated.

Best wishes,

I am trying to produce a scaleable dot-based font family in Fontlab as Mac flavoured Opentype. I’ve had a lot of trouble with getting small circles to be geometrically correct in Truetype (the beziers flatten the arcs) but Opentype keeps them geometrically consistent.

However, I have a bigger problem which I can't seem to fix.

Hey Everybody,
I am trying to have something like a black block underneath every Letter of the typeface . So basically an inverted version of the typeface on a black Background. Is it possible to automtically generate an effect like that in fontlab or give the typeface a feature to do so? The propblem is that the Typeface is not a monospacetypeface so if i would set up the letters on a black background in the glyphsheet , once two letter would overlap like AV something would be cut away from the A or V. It also needs to work witout doing anything manually afterwards ( like changing underline options in indesing for example)! Would be great if anybody could help me!
All the best

Hi all,
Does anybody already saw this display bug in FontLab ?
All the texts you can type in FontLab like values or sample text in metrics window or somewhere else are not displayed in latin characters but in a kind of hebrew or something like that. A bit annoying to be precise !
I already had this bug in iTunes, but this disapeared at the next update.
I tried to reinstall FontLab totally but without succes.
Thanks by advance for the help.


Anyone knows how to remove hundreds of random guidelines?
Is there any macro?, or something?

Thanks in advance!

I'm hoping that someone might be able to assist me with a few FontLab 'OpenType" feature questions:


I'm using Fontlab 5.0.4 on mac os 10.6.4 and I have problems with resize shapes.
When I resize the shapes they are getting damaged and I don't know what to do.

Anyone can help me here??
