Regular Expression question

Hi Ron,

If you have your unicode data in a field, it is always Rev's only  
flavour of unicode, which is mostly the same as UTF16. So, if you  
convert your search string to UTF16 and escape the necessary  
characters, you should be able to use regex on a field.

If you are doing a regex search on unicode data from a UTF8 file,  
without displaying this data in a field, you need to convert your  
regex search string to UTF8 before doing the search.

So, probably, the answer to your question is that Revolution doesn't  
natively support regex for unicode, but there are workarounds possible.
