Message #5 received at submit <at> emacsbugs.donarmstrong.com (full text, mbox):
Emacs (read_escape() function at lread.c file) interpretinterprets
"\x3a480" string as "0x3a480" instead of ":" and "480" coming next.
Some software (most? gnupg to name one) assume these escapes represent
single bytes.
Try interpreting "\x3a480" in the *scratch* buffer.
IMHO the while() loop in read_escape for c='x' should depend on
"count < 3" condition.
Why would anyone use multibyte "\x" sequence instead of "\u" one anyway?

OK, good point. We need a workaround somewhere else (in GnuPG maybe?).
Please consider this bug solved/closed/non-existent.

Then they are broken. The syntax of strings is documented in
(elisp)String Type.
