Details:

The following two messages are same, but the first one produces "invalid
multibyte sequence" warnings, when extracted using xgettext --from-code=UTF-8
concat-literal-hex-escape-01.c (attached):

  gettext("1 foobarqwyx" "\xc2\x9c" "1 fbq");
  gettext("1 foobarqwyx" "\u009c" "1 fbq");

It appears parsing works by first concatenating the literal, and then
resolving escapes, so "...\x9c" "1..." is interpreted as "...\x9c1...". When
e.g. a space is inserted before 1 in the last literal segment, extraction
works (single message in the POT).
