brace '}' (which probably isn't 100% correct), this should be checked in tests
for replace_handle_esc_seq function, not process_escape_sequence - it is the
replace_handle_esq_seq who decides whether it is an escape sequence or not.
Also, \x{4344} is usually a code for wide character (UTF-8), and not for "CD".
So we can either ignore the higher bits, or generate wide character codes...
The second would be convenient, but would also introduce a hard-coded UTF-8 charset.
