> With the introduction of UTF-8 support in the client driver (DERBY-728), the documentation regarding the length of the arguments (RDBNAM, USRID, etc) will become misleading.
> On the list, Kathey has identified [1] one of such spots. Before releasing, we should try to find any other occurrences and fix them accordingly. Please note that the UTF-8 is a variable length encoding and as such, since we are maintaining the 255-byte length cap, the length in characters will now be variable.
> Regular ASCII characters still take 1 byte, Latin and other extended characters take 2 bytes, Chinese characters take 3 bytes and some special characters take 4 bytes. [2]
