Just mentioning this so that anyone else who hasn't noticed yet won't be surprised. You know how a few glyphs automatically get two codepoints because they appear in Latin-1/Mac junk and also in the Greek block? Now, say you open Tools:Actions because you want to slant every glyph 8 degrees, for instance. If you check "Apply to entire font", the action will be applied twice to any glyph with with two codepoints. The mu, Delta, and Omega will be slanted 16 degrees. Depending on how subtle the effect is, the difference could escape your attention for a while.
