Uh uh... problem with generating font

nettoo

Hi,

I recently wanted to generate one font into OTF I made, but some weird things happened.
While generating, at 93% of whole process, in Output panel, it shows me this warnings. After a couple of seconds, it complete whole 100% process of generating and I can see OTF file, but when I try to double-click on it, it shows an error (file is corrupted).

I see that there are a lot of "removing duplicate glyph" in Output panel, but I can't find the reason why that appears.

One more thing... I tried somehow to bypass this errors by generating font first into Win Type1 (PFB) and then from PFB > OTF. It works, I can install font and on double-click I can see "Quick brown fox...", but... it looks like some kerning pairs are missing or are incorrect (not like they are in original VFB file), meaning this is not the solution for this problem.

I need help :)

P.S. - Sorry for such a looooong post.

OK, I think I missed the lesson from generating classes.
This definitely has something to do with it.

Mark Simonson

A glyph may only be used in either

- a single kerning class that is used for both left and right sides of a kerning pair, or
- in two classes, one that is used for the left and one that is used for the right.

The errors you're getting indicate that you have the same glyphs in more than one class and that they conflict (that is, the classes are for the same side of a kerning pair).

It'd be nice if FontLab would warn you when add the glyphs to a kerning class rather than when you try to generate the font, but it doesn't, so you just have to be careful.

There is also a "Clean Up Classes" command in the Classes panel, which should help with your problem, but it can't read your mind and my not give the kerning classes you want.

nettoo

That's definitely it.
Thanks!

What a mess is there now. Uh uh... The only normal & reasonable solution to be sure that everything would be done correctly is to remove all old "classes" and start from the beginning.

OK, no time for crying, back to work, that's the only thing left now to do :)
Thank you once again Mark!

nettoo

Hm, one more thing I just noticed.

I opened this file which gives me classes errors and in "Classes" panel I clicked "Generate Classes..." (with selected Default options (selected "Generate metric classes", "Generate kerning classes", "Do not mix characters from different scripts in the class".. everything else I leaved unchecked).

This is what do I get in "Classes" panel:

After that, I just Generated file again and it made OTF without any problems?!

Now, I have doubts... was this what I did done on right/correct way?

Mark Simonson

I never use the "Generate Classes" command (I prefer more control than that), but I assume it wouldn't generate classes containing errors. It's not right or wrong to do it one way or the other, it just depends on how much control you want.

Jens Kutílek

When trying to find the problem, you can ignore the metrics classes. They aren't used when generating a font, they are just a FontLabStudio-internal thing to help with spacing.

To check for errors/overlaps in your kerning classes, you can use the Yin Yang button in the Kerning Assistance dialog (Tools - Kernin Assistance).

nettoo

That's it baby :)

Damn... it took me half day to figure it out.
Problem was next:

- "Kerning Assistance" was activated! Actually, it included pairs from FontLab's sample that had all sorts of glyphs - Greek, Cyrillic... and this font I made have only basic glyphs, so that made problem during generating. I saw that some of the classes were empty, and not selected either left nor right side-bearings. So I just copy all glyphs into new font file from the old one and I exported metrics from old one and imported it into new one = and that's it!

Mark, thank you for your help, it was very stressful, but useful experience. And I learned something new today.

Ciao ;)

nettoo

Thanks Jens. I'll check that too now.
