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.
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
by these glyphs:
[0 1 1072 870 7 0 7 7 1 nil]
[0 1 769 646 7 2 6 10 -7 [-8 -1 -8]]
Character code properties: customize what to show
name: CYRILLIC SMALL LETTER A
general-category: Ll (Letter, Lowercase)
decomposition: (1072) ('а')
There are text properties here:
charset cyrillic-iso8859-5
face font-lock-string-face
fontified t
