I'm guessing that where I see four characters "<92>", the actual file
has a single character. Some tools render unusual characters that way.

I'm not sure I know what you mean by "works". It seems to be replacing
every ampersand with an ampersand in the target string, which would be
a no-op if it didn't have side effects.

It doesn't? It's probably matching any true apostrophes.

I think you're looking for one of these:
s/\x92/'/g
s/\x92/'/g
tr/\x92/'/
Backslash escapes are documented in perlop. Hope this helps!
