Thu 26 Feb 2004 11:07:16 AM UTC, comment #2: This seems to be a documentation bug, more than anything. The Grammatica RE:s support unicode character references in the following way: \uFFFF (where FFFF is the Unicode hexadecimal code) So the example above would be expressed in the following way (untested): Char = <<\x09\|\x0A\|\x0D\|[\u0020-\uD7FF]\|[\uE000-\uFFFD]>> Note the use of \x for two-character hexadecimal encoding and \u for four-character encoding. Also note that the character sequence [#x10000-#x10FFFF] has been omitted, see bug #7916 for more information.	Per Cederberg <cederberg>

Tue 24 Feb 2004 04:01:53 PM UTC, original submission: One consequence of not using SDK built-in regular expression support is that unicode support is not available. For example, the XML grammar defines Char as follows: Char ::= #x9 \| #xA \| #xD \| [#x20-#xD7FF] \| [#xE000-#xFFFD] \| [#x10000-#x10FFFF] How could that be expressed with grammatica? If it supported built-in regex engine, this would be no problem (in .NET at least :o) BTW: I'm seeking for an XML/RelaxNG parser.	Anonymous
