Check for Unicode Categories

Hi,

what I am trying to do is to check in ABAP a given URL for characters from certain UC categories.

For example, I want to check if an input characters belongs to category [L], which is actually consisting of the (sub) categories Ll, Lm, Lo, Lt and Lu.

There are thousands of characters in these categories.

In Perl, for example, a regex for checking for a lower case letter would simply look like this \p{Ll}, but that does no work in ABAP regex.

Does anyone had such a problem before or even a solution for this in ABAP?

Thanks, Otto
