Hi Guys, A quick question. I'm trying to interpret unicode code-point ranges from the CSS 3 spec - http://www.w3.org/TR/css3-syntax/#CHARSETS
The rule in question is nonascii :== #x80-#xD7FF #xE000-#xFFFD #x10000-#x10FFFF Where (I think) these are unicode code-point ranges. The latest rakudo build is fine with: % perl6 -e perl6 -e '/<[\c[0x80]..\c[0xD7FF]]>/' ...but doesn't like the second (or third) range: % perl6 -e '/<[\c[0xE000]..\c[0xFFFD]]>/' ===SORRY!=== Invalid character for UTF-8 encoding ...the individual code points are ok: % perl6 -e '/<[\c[0xE000]]>/' % perl6 -e '/<[\c[0xFFFD]]>/' I'm think I'm getting the above error because not all unicode code-points are defined for the range xE000 to xFFFD - see http://www.utf8-chartable.de/unicode-utf8-table.pl . I'm just having a problem implementing a concise regex/grammar rule for the above. Looking for advice. Cheers, David Warring
