URI::decode and unicoded characters

When using URI::decode to filter uri-requests it seems like unicode characters such as C3%B6 (which is letter "ä") gets decoded into the two characters "├Â" instead of being kept as is.     ...

It seems like the TCL engine (used for irules by F5) will automagically turn any char that starts with %3C into a unicode character internally. This means that running "string map" and searching for %3C simply just wont work since the %3C character has been converted into some other combination.

 

 

So once I figured out the codings (thanks to http://dimsboiv.uqac.ca/index_addon/utf-8.html) I could manually handle the missing characters.

 

 

But yes it would be better if the URI::decode function could do this for you.

 

 

Is it possible to contact the F5 support without first register an account?
