It appears that SL new servers just deployed did change the way linked messages are communicated among objects so that my internationalized utf-8 boards are NOT more working correctly and not able to display European chacters.
NEWS: I found out which exactly was the reason for the breaking down. This was due to the modifications in February when LL did restrict the llSetObjectDesc to be only 127 chars AND no utf-8 chars in it.
I needed to rewrite the LSL code to avoid the use of llSetObjectDesc.
Stay tuned to know when I can give you a definitive solution for this problem 😦
