There is a bug in the string table processing feature of the graphics library. When a compressed string table is used to get a string, in certain cases where a compressed string composes the first part, and an uncompressed string composes the final part, the length is improperly calculated and a null character is placed after the compressed portion. This is solved by commenting out the if statement on line 2816 like so:
//
// If we had not copied any characters before hitting this case,
// initialize the output pointer (this keeps the code at the end of
// the function that returns the length happy). This will be the
// case if we are using an uncompressed string table.
//
// if(!pui8BufferOut)
// {
pui8BufferOut = (uint8_t *)pcData + (i32Idx + i32Buf);
// }
This allows the buffer pointer to be set to the end of the uncompressed portion of the string allowing the length to be computed, and as a result, the null terminating character to be placed at the end of the total concatenated string.
