Description HansPL 2010-07-19 02:58:34 UTC
In DejaVuSerif-Italic.ttf and DejaVuSerif-BoldItalic.ttf, Ver. 2.31,  the italic kyrillic glyph U+0434  'д'  is totally wrong.  (Noticed in OpenOffice when toggling between Book and Italic).

Looks fine to me in 2.32, could you please elaborate? Please note that the Serbian/Macedonian alternative is also available through the OpenType 'locl' feature (depending on software and language tagging).

Comment 3 HansPL 2010-09-02 01:49:20 UTC
Please see attached a screenshot from OpenOffice 3.2.0 in WinXP:  
I've entered the three lowercase kyrillic letters Ghe, De and Ie (U+0433, U+0434, U+0435) and the corresponding uppercase letters (U+0413, U+0414, U+0415) in DejaVuSerif 4.31;  then again (copy&paste) formatted to Arial Unicode MS for comparison.  

The first line is formatted in Book,  the second line (copy&paste from the first) formatted to Italic,  the third to Bold,  fourth BoldItalic.  As you can see,  the lowercase De (and Ghe) change to a totally wrong glyph when toggling to Italic (and back when toggling back to Book).  Therefore I assume that there is a mix-up of some glyphs in DejaVuSerif-Italic.

"д" does change shape like that in italic. There are more such glyphs, like "т" which turns into an "m"-like shape. You get a similar effect with Latin "a" in many italic fonts. Italic styles try to reflect hand-written letters a bit, so that's why they change.

You don't see that change in Sans because that doesn't have an italic style, only an "oblique" one (i.e. only slanted).

(And to my knowledge there's also no italic/oblique variant of Arial Unicode MS  -- the one you see is just generated by your font renderer -- so no chance of different shapes there anyway)

The following links should clear up the confusion:

- http://de.wikipedia.org/wiki/Kyrillisches_Alphabet#Kursive_und_aufrechte_Formen (in German)
- http://en.wikipedia.org/wiki/Cyrillic_alphabet#Letterforms_and_typography (in English)

Oookay...  so this is really correct!  It looked very confusing to me,  being no native.  
Thank you both for the enlightenment (it's never too late to learn something new),  and sorry for the unfounded nuisance!
