The capability to escape/unescape unicode hex, formerly in fromAscii() and toAscii(),
has been rolled into escape() and unescape().

The flag parameter in escape() determines treatment of non-ascii bytes in the
input.  If flag==2, then legal utf8 will be escaped as one or two "\uHHHH"
escape sequences. If flag==1 then non-ascii bytes will be escaped as plain hex, 
like "\xHH".  If the flag==0 then only control-codes in the input will be escaped.

This is useful if the consumer of the string can actually print normal UTF8 characters.

The new implementation of unescape() now knows about \uHHHH and knows how to deal with
escaped surrogate pairs as well.
