I am interested in how well your TMask version compares with Delphi's
version.
Does it match the speed or even surpass it?

Anyway this unit looks very promising!
It works with Unicode as advertised. It passes all cases in the updated
unit test. Our current implementation fails miserably.
See components/lazutils/test/testmasks.lpi
For example this
  TestMask('ö', '[!☺-☂]', True);
means that 'ö' is not between a happy face and an umbrella.
Case-insensitive matching of Unicode can be fixed later with functions
found in LazUTF8.

With José's approval the license will be LGPL with a linking exception. It
will be part of the LazUtils package. Author's name will be mentioned of
course.
Is that OK?
I will not copy the whole original unit but use the UTF-8 parts + rename
and tweak some things.

Juha
