IDN Support suggestion about registered-domain-libs

I found an issue on above regexp, that validation regexp doesn't appear to match for Indian tld's like, although 99% of the rest has worked.

ಭಾರತ     xn--2scrj9c
ଭାରତ     xn--3hcrj9c
ভাৰত     xn--45br5cyl
भारतम्    xn--h2breg3eve

I tried varying the regexp but not finding one that works, using \p{Devanagari} without success.

Maybe will have to go through the ascii domain instead to avoid these vocabulary challenges.

@wadih, thanks for your feedback and research: in 9fccafa I simply disabled the domain label length validation and the regexp to prevent false analysis.

I tend to change the processing so there is a second suffix tree being encoded to ACE and all checks including length validation and character validation are done in ASCII. Downward compatibility should be kept.
