That's the recommendation in https://en.wikipedia.org/wiki/Cyrillic_script_in_Unicode > the terminal emulator (at least URXVT) will combine the accent and the > vowel into a single glyph. xterm(1) does too. libvte-based terminals seem to place it on the line above!? > This approach of adding accents causes problems with tbl, though. The > combination of the two characters into a single glyph screws up tbl's > (and/or Groff's) assumptions. For instance, in a table like: > | саморазруше́ние | > | foo bar | > the bars won't properly line up. It boils down to persuading `\w', used by tbl(1), that the U+0301 takes no space. $ groff -Tutf8 >/dev/null .nr w \w'A' .tm \nw 24 .nr w \w'\[u0435]' .tm \nw 24 .nr w \w'\[u0435]\[u0301]' .tm \nw 48 $ Tricks like overstrike with `\o' and moving left with \h affect the \w but don't give the desired output because grotty(1) also processes them. > For instance, \[u0435_0301] should theoretically also format as an > accented Cyrillic e.

I think those are mapped onto their Unicode rune, and as you start by saying, then isn't one for U+0435 combined with U+0301. $ cd /usr/share/groff/1.22.3/font/devutf8 $ grep 0435 R u0435_0300 24 0 0x0450 u0435_0308 24 0 0x0451 u0435_0306 24 0 0x04D7 $ grep '0045.*0301' R u0045_0301 24 0 0x00C9 u0045_0304_0301 24 0 0x1E16 u0045_0302_0301 24 0 0x1EBE $ I look forward to solutions and workarounds from the others here. :-) -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
