From 4e04afc2df9bbc26e5ab524b53a6f4f1e61d7c9e Mon Sep 17 00:00:00 2001

Subject: [PATCH] ucs2.h: fix logic that checks for UCS-2 string termination
Currently the loop to count the lenght of the UCS-2 string ends if either
of the two bytes are 0, but 0 is a valid value for UCS-2 character codes.
So only break the loop when 0 is the value for both UCS-2 char bytes.

Subject: [PATCH] ucs2.h: remove unused variable
The const uint16_t pointer is not used since now the two bytes of the
UCS-2 chars are checked to know if is the termination of the string.
