Hi
Consider the Ex command ":s/ \?/ /g".
It transforms a line "foo bar" into " f o o b a r " (good so far).
Now, if the line contains multibyte characters, it no longer works.
If current line contains "café bar" for example, it transforms it
into "c a f<c3> <a9> b a r" (bad).
Tested with Vim-7.3.177 on Linux with a utf-8 locale.

Yes, apparently, \? not only matches everywhere (which is expected), it
even matches between individual bytes of a multibyte UTF-8 codepoint
(which I wouldn't have expected). OTOH,
:s/./\0 /g
correctly yields "c a f é b a r ", showing that the dot did match the
two-byte e-acute as a unit. This suggests a workaround:
:s/./ \0 /g
followed by
:s/ \+/ /g
should (untested) result in having nonspace characters separated by
exactly one space each, with one space at the start and end of the line,
but without inserting anything in the middle of multibyte characters. I
don't know how it would handle composing characters though.
Best regards,
Tony.
