I have addressed any "dodginess" by
commit a8f4b0c691d6f1b08948976e74087b646bf8c6ef

Improve heuristic for UTF-8 detection in "$!"
Previously, the stringification of "$!" was considered to be UTF-8
if it
had any characters with the high bit set, and everything was
syntactically legal UTF-8. This may incorrectly guess on short
strings
where there are only a few non-ASCII bytes. This could happen in
languages based on the Latin script where many words don't use
non-ASCII.
This commit adds a check that the locale is a UTF-8 one. That
check is
a call to an already-existing subroutine which goes to some lengths to
get an accurate answer, and should be essentially completely
reliable on
modern systems that have nl_langinfo() and/or mbtowc().
