i want to submit to you an issue that actually is driving me mad. I spent a lot of time trying to solve it without results.
After all design process with fontlab (letter design, metrics, kerning, autohinting) i have now a complete font family of 9 weights (plus their italic version) that seems to work well with a simple fontlab exportation, both TTF and OTF. At this point i want to export with TRANS TYPE 4 ( TTF, OTF, Web font TT) in order to obtain a cross platform package.
The problem become visible now:
after the Trans Type exportation if i try to use the font (with illustrator for example) i found missing glyphs like /I or /K or /B in some weights but not in other (example: missing in light version but not in the regular version)
Which kind of problem is this?
Is the fontlab file that is corrupt? or it's a problem with transtype ? (i have made TT exportation many other time without encounter any problem), or is an hinting problem?
(I know i can export with fontlab without using Trans type but i really want to know why this is happening!)
I appreciate any advice you can give me.
Many thanks for your attention![Additional Information:1. made a set ps direction to all glyphs and remove overlap2. i didn't decompose every glyphs 3. i made a autohinting, autoreplace then i set standard stems and auto zones]
PS Sorry for my english
