I have started to extend "pcre" for wide character string handling
(strings may consist (uniformly) of either 1, 2 or 4 byte
units; thus this is a fixed width (UCS-2)
rather than multibyte (UTF-8) approach).

Currently, I require, that all RE metacharacters are still
ASCII; e.g. in "{n,m}" I would only recognize ASCII
digits but not ARABIC-INDIC digits. There is, of cause, no
restriction with respect to the characters that match themselves.
Things like canonical mapping and canonical writing direction
are not handled (it is more a wide character than a unicode support PCRE).

Of cause, I will announce the module, as soon as it becomes
alpha. I make, however, only slow progress.
