Re: Potential Bug with BIZ UDGothic Font

[Hin-Tak Leung]

That would not be a bug in FreeType, but a bug in the Font. You need to report it to where you got the font from . From the look of it, that would be the hinting instruction and/or drop-out control in the font. FreeType is showing the font as its hinting instructions tell FreeType to. The difference between LIGHT and NORMAL is that some hinting instructions (in the font) are processed differently in the two modes. Again, this is a problem with the hinting instructions within the font, and you should report it as such.

You'll find that if you switch off hinting (one of the options in ftview) , the problem is gone. This, shows that the bug is in the font, and specifically in its hinting instructions.

Hi,

I believe there is a bug with the BIZ UDGothic font, specifically with the '–' character when using a small font size.

The issue was found in version 2.13.3.

I managed to work around the issue by using FT_LOAD_TARGET_LIGHT instead of the default parameters.

 

Additionally, I was able to reproduce the problem in ftview.exe.

No bug


With the bug:


Best regards,
Simon
