I think the problem is triggered by displaying the u+0301 acute accent above the а (to show the vowel with the accent).

Does Menlo has a > glyph for that codepoint? Yes, Emacs seems to think that the composed character takes up no space. This may be no help whatsoever, but I've attached another image showing a cyrillic a with acute alongside the latin version. The latin one is not, afaik, composed, because I don't know how to do that. Both have spaces round them. I don't know how to check whether the font supports it.

The latin > one is not, afaik, composed, because I don't know how to do that. The Latin character is composed, because Emacs knows how to do that. You can verify with "C-u C-x =". Can you tell what does window-text-pixel-size return for the а́ part of the text, both with Menlo and with Monaco? > I don't know how to check whether the font supports it. > Here's what describe-char says: > > position: 148 of 234 (63%), column: 2 > character: а (displayed as а) (codepoint 1072, #o2060, #x430) > preferred charset: cyrillic-iso8859-5 (Right-Hand Part of ISO/IEC 8859/5 (Latin/Cyrillic): ISO-IR-144) > code point in charset: 0x50 > script: cyrillic > syntax: w which means: word > category: .:Base, L:Left-to-right (strong), Y:2-byte Cyrillic, c:Chinese, h:Korean, j:Japanese, y:Cyrillic > to input: type "C-x 8 RET 430" or "C-x 8 RET CYRILLIC SMALL LETTER A" > buffer code: #xD0 #xB0 > file code: #xD0 #xB0 (encoded by coding system utf-8-unix) > display: composed to form "а́" (see below) > > Composed with the following character(s) "́" using this font: > mac-ct:-*-Menlo-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The above line says that Menlo does have the glyph for the accent.
