Please help: Integrating Arrows

DontKnow's picture

Hello Forum,

I am stuck at one point in FontLab and hope someone can help me.
I would like to integrate arrows in a TrueType font using FontLab: arrow right and arrow left.
The font should be used as a webfont later and i don´t want to build in images for arrows anymore.

To achieve this I proceeded as follows in FontLab:
- Create a Glyph in an empty grey box wich is marked yellow in the font-window
I understand that glyphs, that are not yellow do not belong to the currently selected encoding, codepage or Unicode range
- then i rename the glypgh-name to "arrowright" (using the context-Menue) and generate the unicode index for it (2192) using the little diamond
- After that action the Glyph is marked as grey (unencoded?) and it goes to the end-section in the font-window.
The arrow does not appear in the exported font. I tried TrueType and OpenType.
The font consist of 234 glyphs.

Do you have any ideas, what i am doing wrong?
Does the unicode codepage not support arrows?
I would be grateful for any hint.

Since none of the more knowledgeable have replied, I'll give a try. What you have done should work, always assuming I've understood you aright.

First of all, you are creating (generating) an OpenType font, right? You're using

TrueType/OpenType TT

in the "save as type" window.

Beyond that:

I understand that glyphs, that are not yellow do not belong to the currently selected encoding, codepage or Unicode range Yes, but this is only internal to FL's display. It is a convenience in using FL, not a requirement; the "yellow" has no other meaning.

The glyph should ultimately have a name of "arrowright" and a Unicode number of 2192, though actually, a name of "uni2192" is also correct. Make sure it shows in the metrics window, just as a check that everything's hooked up.

Then, after you have saved the .vfb file and complied the features (if there are any), go to the preview panel, and type in

\2192

It should show. Check the name assignment by typing in

/arrowright (or /uni2192, if you've *named* it that)

Your character should show both times. It should also show in the metric window BTW, with the same strings.

BTW-2 Unicode is not a "codepage" If you're filling in the File > Font Info > Encoding and Unicode section, I believe the conventional wisdom is to select "Latin 1," and use "Macintosh MacRoman" for the Microsoft Character set. Though I know that "Western (Latin1)" also works...

If this is what you have done, then I'd ask what applications programs have you used to test the font where the character failed to appear?

Dear Charles,
thank you for your detailed answer!
It helped me very much, since i have not much to do with fonts.

Especially your last note has encouraged me to check the font (TrueType / OpenType TT) in the FontExplorer X Pro. There I could see that the name of the Arrow did not work, it was just empty (only the Glyph-ID has a number, but also a different one). Weird, because the Metric preview window displays everything correctly in FontLab. Also "Latin 1" + "MacRoman Macintosh" are adjusted properly in the Font Info.

Then I generated an OpenType font (OpenType PS) and the FontExplorer shows the names properly. After that i use Font Squirrel to generate the web font, and the arrow does not appear in the glyph overview of the demo HTML - despite the OpenType PS. Argh. I came up with the idea that this could be an issue of Font Squirrel and give another Generator a try (web-font-generator.com). Now it seems to work!

I really admire the patience and the many skills font designers need to have.
I was very confused by the yellow marks in FL ... Thanks again for your time and help!

Hmm. When you talk about "FontSquirrel," I suspect your making woff format fonts for the web?

Special issues there, and I know almost nothing about those formats. For checking the font itself, try using Microsoft Word (post 2010), or any OT-savvy text editor, and a laser printer -- actually, I'd use InDesign, but that's expecting a bit much, I know.

If everything works as it should in print, press on to the web formats. I did find one tidbit about FontSquirrel & it's generator:

When using the FontSquirrel Webfont Generator, you need to check the radio button “EXPERT” and then select the languages to be supported or the code range. The default is that only characters used in “Western languages” are included.

For all I know, the Font Squirrel generator is not picking up that information from the font itself. Nor do I know what "code page" arrowright lived on, back in the dark ages when there were "code pages" for hard-wired encodings. But we're well outside the area where I know anything, so...

Yes, i want to extend the web-font with arrows for not using ugly text-images.

The hint with the Expert-Mode was it. In this section i could put in the arrow-sign in a form for including Single Characters. Putting the Hex-Code in the Unicode Ranges-form doesn't work, but a simple copy of the symbol has done it. It makes of course sense that webfonts do not included all characters for being small.

Tomorrow i will print the font through Indesign for being sure that everything ist working correct.
I am very grateful, thank you so much again :-)
