-------------------------------------

Hi [~Sebastien],

Currently I'am evaluating this issue and I think the first and second ({{\\x10000-xEFFFF}}) mention points are both bugs.
But especially for second I have to re-check which unicode characters are allowed in the OData specification.

However a short question for your test class.
When I run it with JDK 6 I get following exception:
{code}
Caused by: java.util.regex.PatternSyntaxException: Illegal hexadecimal escape sequence near index 154
^[:A-Z_a-z\u00C0-\u00D6\u00D8-\u00F6\u00F8-\u02ff\u0370-\u037d\u037f-\u1fff\u200c\u200d\u2070-\u218f\u2c00-\u2fef\u3001-\ud7ff\uf900-\ufdcf\ufdf0-\ufffd\x{10000}-\x{EFFFF}][:A-Z_a-z\u00C0-\u00D6\u00D8-\u00F6\u00F8-\u02ff\u0370-\u037d\u037f-\u1fff\u200c\u200d\u2070-\u218f\u2c00-\u2fef\u3001-\udfff\x{10000}-\x{EFFFF}\uf900-\ufdcf\ufdf0-\ufffd\-\.0-9\u00b7\u0300-\u036f\u203f-\u2040]*\Z
{code}

Which Java version do you use?

Best regards,
Michael

> It’s seem that are some issues with regular expression in class EdmNamedImplProv.
>  
> The first one is about \\u00C0\\u00D6 part. It should be \\u00C0-\\u00D6 as it’s only alphabetic characters.
> With current implementation Õ Ä can’t be used but Ö À can be used.
>  
> The second issue is about \\x10000-\\xEFFFF, range only available for first character, but not the following ones (another bug ?).
> \x????? is not supported in regular expression.
> It should be \x?? (2 and only 2 characters) or \x{?????}.
> This part is splited like \\x10, 0 (twice), 0 to  \\xEF, F (3 time).
> This make some characters valid at first position like numeric characters or "×" (\u00D7) multiplication sign.
> But at the beginning of the expression there is \\u00C0\\u00D6\\u00D8-\\u00F6, means that \u00D7 should not be allowed.
