Hi list

I want to test membership of a unicode char in a set / array of unicode chars. Something like

var ucCh: unicodechar;
if ucCh in [ UnicodeChar('0')..UnicodeChar('9')] then
    dosomething;

I am using fpc 2.6.0 and the '..' operator converts the data to a pascal set, which is limited to 1 byte data.

Is there another way?

Thanks
Wimpie

if (ucCh >= UnicodeChar('0')) and (ucCh <= UnicodeChar('9')) then
dosomething;

Delphi has CharInSet() function for this:
@TSysCharSet.html

I don't remember whether we have it in FPC at the moment.

In our previous episode, Paul Ishenin said:

2.6.0 has it iirc, but before you point to that, it only checks the low byte. IOW it is a stop gap, not a solution for set of char in the unicode world.

Since unicode printable characters are effectively strings, if you want a pure set you will probably have to treat it as a hash or so.

Thanks, I had already written a CharInSet(UnicodeChar; UnicodeString) function, but I hoped there were a language construct equivalent to the ansi char method.

Don't know if it can be helpful for the OP, but some years ago, I sent 'Unicode category membership checking functions' here: http://bugs.freepascal.org/view.php?id=16400

Please feel free to use that code for whatever you want w/o restrictions.
