Braces regular and bold misalignment

[xsrvmy]

The hinting of the braces causes the normal and bold variant to be misaligned. This is at point size 12 without hidpi. Presumably this has something to do with hinting.

ttfautohint's "reference font" feature (that unifies blue zones) always fails on my system :(. So I have to process each subfamily separately (which produces non-unified blues).

Maybe a bug in TTFA?

Hmm... might try calling ttfa myself then since I am compiling a customized version.

[lemzwerg]

@be5invis, this is easily possible :-) Please be more specific what problems you encounter, ideally with a test case that I can check.

This command (on win32)

ttfautohint -R .\dist\iosevka\ttf\iosevka-regular.ttf .\dist\iosevka\ttf-unhinted\iosevka-bold.ttf .\dist\iosevka\ttf\iosevka-bold.ttf

... gives me this error message:

An error with code 0x02 occurred while loading the reference font
 unknown file format  

Not sure whether it is platform-specific.

Using ttfautohint 1.8.4.

Ran into the same bug (ttfautohint -R/--reference fails on Windows) and finally found the cause:

https://repo.or.cz/ttfautohint.git/blob/HEAD:/frontend/main.cpp#l1387

reference = fopen(reference_name, "r");

The reference font is a binary file and should be opened with "rb", otherwise it will be corrupted on Windows. Making this change fixes my local build of ttfautohint-1.8.4 on MSYS2 UCRT64.

I don't know if control = fopen(control_name, "r"); should also be opened with "rb" or not.

I haven't reported upstream to FreeType/Werner Lemberg yet. @lemzwerg you could fix this directly, or I or @be5invis could make a post to freetype-devel@nongnu.org.

[lemzwerg]

Thanks a lot! I've pushed your fix to the ttfautohint repository.

[be5invis]

@lemzwerg Do you have plan for next release?

[lemzwerg]

No plans yet, sorry.
