It was brought up that my explanation was confusing, and I agree it is. So I'll try again. The following should return #t: (regexp-match? #px"\\u{E0}" "\u00E0")(regexp-match? "\\X" "\u00E0")(regexp-match? "\\u00E0" "\u00E0")(regexp-match? "\\x00" "\x00")(regexp-match? "\\n" "\n")(regexp-match? "\\r" "\r")(regexp-match? "\\t" "\t")(regexp-match? "\\a" "\a")(regexp-match? "\\e" "\e")(regexp-match? "\\f" "\f")(regexp-match? "\\v" "\v") Note: the \\u{E0} syntax is Perl-specific, I believe, so it should probablyonly be enabled for pregexps, not normal regexps.
