[gobo-eiffel-develop] Further problems with regular expressions on Unicode data

[Colin P. A. <co...@co...>]

The re @.@ matches two @ characters separated by a single character.

If that character is a non-ascii Unicode character, then the trick
Franck suggested of replacing both the data and the re with their
utf-8 byte sequences doesn't work, as the . will match only one byte.

You'll have to replace '.' by it's uft-8 equivalent.
Something like that:

  ([\0-\9]|[\11-\x7F]|([\x80-\xFF][\0-\x7F])|......)

I guess you see what I mean.
