Subject: 23.1; Problem of rendering cyrillic fonts on Mac OS X
Date: Fri, 31 Jul 2009 12:11:36 +0400

Hi.

`Terminus' font for russian language is broken.

I checked for Emacs 23.0.90-23.0.94 and it works. Emacs  
23.0.95-23.0.96 makes bold font instead regular font (see bug #3834).  
Emacs 23.1 has normal rendering for english language, but for cyrillic  
languages font is broken.

For recreating problem:
1. Install TerminusMedium.dfont from http://www.fileqube.com/file/zLiajO207525
2. In Emacs 23.1.1:
   ns-popup-font-panel <RET> ; choose Terminus font
   C-h h ; show multilingual text (see russian text)

Here is a screenshot of incorrect rendering:

Here is a screenshot of correct rendering (Emacs 23.0.94):

Hi,

please check C-u C-x = on the characters in question and let me know  
what font they are actually using.

(I suspect the problem is Emacs.app is now paying more attention to  
what the font itself says it has characters for, but I'm not sure.   
Another test, try using Cyrillic characters with Terminus in TextEdit.)

thanks.

Terminus font (english and russian layout) works very well in  
TextEdit.app.

Hi.

It's very strange :-( It's my Font Book's info (Mac OS X 10.5.8):

Hi all,

Any updates on this problem? I'm still experiencing this with GNU Emacs 
24.2.1 (x86_64-apple-darwin12.2.0, NS apple-appkit-1187.34), see 
screenshot attached.

With best regards,

Lev.

Hi, are you still having this problem with recent builds of Emacs? As I
understand it the font back-end was completely replaced sometimes since
this bug report was originally made, so hopefully that solved it, if it
wasn't already fixed.

Sorry, no idea. I no longer have an apple computer, and have no means to
verify.

Since there doesn't seem to be anyone left responding to this who can
confirm if it's still an issue or not, I'm going to close.

Thanks.
