My problem is that i dont know how to implement with the specific set of non ASCI characters. Should i create a set of the non ASCI characters and iterate through the string? Any ideas?

Answer 1

In XSLT 2.0 or higher you can do:

replace($yourString, '[^\p{IsBasic_Latin}]', '_')

to replace all non-ASCII characters with an underscore.

Note that this will preserve all ASCII characters - including non-printable control codes.
