base64encode/decode Umlaut Errors

[fishgod]

Running the following Code in the addressbar:
::msg base64decode(base64encode("ÄÖÜäöüß"));
results in this message-box:

What's up with the encoding of these German Umlauts? Why are the lowercase äöü-letters working, but not the upper-case?

In my script the base64-encoded data is written to a file and read from another instance, but that does not matter when allready in this simple example things do not work right.
This has been working right somewhere before Version 24.x if this helps.

Confirmed and fixed. Good (and shocking) find! Next beta...
