[\\u0600-\\u06FF]
\\ is a literal \ so I that matches
any one of characters \ u 0 6 F and all characters in the range 0 to \,
except that 0 is char 48 and / is char 47 so this range is empty.
You don't need the u-notation to enter code points into regexp (and
they don't work) as you can just enter the characters directly, or if
you want an ascii representation use xml character references,
& # x a b c ;
These are not mentioned in the regex syntax as they are not really part
of that syntax they are expanded to the character by the XML parser
before XSLT starts.
That's why I doubled the "\" character. Is this doubling spec-compliant ?
\\ is spec compliant but means a literal \.
