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).
