[ragel-users] How to convert [#x2070-#x218F] to Ragel grammar?

[Iñaki Baz Castillo]

Hi, I'm creating a parsing for XML Xpath but in the grammar specs I find:


http://www.w3.org/TR/REC-xml/#NT-NameStartChar

NameStartChar  ::=  ":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] | [#xD8-#xF6] |
                    [#xF8-#x2FF] | [#x370-#x37D] | [#x37F-#x1FFF] | 
                    [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] |
                    [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] |
                    [#x10000-#xEFFFF]


http://www.w3.org/TR/REC-xml/#NT-NameChar

NameChar       ::=  NameStartChar | "-" | "." | [0-9] | #xB7 |
                    [#x0300-#x036F] | [#x203F-#x2040]
	


I've no idea of how to convert them to Ragel grammar. Of course the following 
conversion is wrong:

  [#x2070-#x218F]  =>  0x2070..0x218F

as Ragel complains "literal 0x2C00 overflows the alphabet type".


Any help please? Thanks a lot.
