Hello,

I have a problem with unicode strings. In the language reference
(section 6.6), it is said:

Constant strings which consist solely of characters in the range
0X..0FFX and strings stored in an array of SHORTCHAR are of type
Shortstring, all others are of type String.

The problem is that it is impossible to create a constant string whose
characters are outside the range 0X..0FFX. The compiler procedure that
reads constant strings (DevCPS.Str) uses SHORTCHARs instead of CHARs
and, so, is unable to fulfil the requirements of the language reference
(see an example below).
It's a severe limitation to the use of unicode strings in BB. Questions:

- Has anyone been able to use unicode with BB?

- Would it be difficult to modify the compiler, so that a real use of
unicode becomes possible?

Cheers.

Gérard
