I took liberty to move this to workers.

In case it rings the bell for anyone. Here are prompt lengths computed by
zsh for phil's prompt in ru_RU.UTF-8 locale (where there were the same
results for en_US.UTF-8 as well, so at least proper UTF-8 part is correctly
computed :) )

(gdb) p rpromptw
$1 = 12
(gdb) p lpromptw
$2 = 9
(gdb) p lprompth
$3 = 2
(gdb) p rprompth
$4 = 1

that's absolutely wrong. The actual prompt lengths are (see screenshot)

lpromptw = 13
rptomptw = 16 (it has one space in it)

this perfectly correspnds to something (zsh?) ignoring invalid characters
with high bit set. In both left and right prompts there are exactly 4 of
ACS chars.

I attach both left and ritgh prompts as well.
