Everything looks correct to me. perl says the string is a utf8 string, so it isn't chopping off any bytes. The round tripping of the string confirms that. The string contains a character whose unicode code point is U+00C4--as reported by perl, yet you say your experiments show that a regex of \x{0100} matches that character. I don't see how that's possible, and I don't get a match when I try it. I don't have any more ideas. Sorry. The last thing you might want to do is post your OS, as well as the output from perl -v and perl -V, then see if someone with a similar setup gets the same regex match that you are seeing. Here's my info:
