[web2py] How to handle non-ascii characters in validator IS_IN_SET(...)?

[anton.mue...@gmx.de]

Hello Everybody,

I will post the same code snippet twice to handle two completely
different questions.

In this thread I would like to as the following question:

The Validator IS_IN_SET(...) cannot handle language specific special
chars

There allready were threads "Validators and non ASCII characters"
http://groups.google.com/group/web2py/browse_frm/thread/db9dc637f15984c8/ea025f1d102698f2?hl=en&lnk=gst&q=umlaut#ea025f1d102698f2

and "IS_IN_SET multiple=True with non-ASCII character failed"
http://groups.google.com/group/web2py/browse_frm/thread/545ccff33c370f9b/b779e15fd9ce6949?hl=en&lnk=gst&q=unicode+IS_IN_SET#b779e15fd9ce6949

on groups.google.com. The second thread offered a solution, but it
seems to me not satisfying. Is there any other possibility to solve
this issue?

What is the reason that the validators cannot handle non-ascii
characters (while python can...)?

Thanks for helping!

Best regards and greetings from sunny Bavaria,
Toni


And here comes the code (again):
