# Byte 5 indicates a UCS2 character offset to the base pointer of '15',
# expressed in binary as follows 001 0101, which, when added
# to the base pointer value results in a sixteen bit value of
# 0000 1001 1001 0101, i.e. '0995', which is the Bengali
# letter KA.
# Byte 6 / 7 were not defined in TS102221 example, so just repeated 5
# Byte 8 contains the value 'FF', but as the string length is 5, this
# is a valid character in the string, where the bit pattern
# 111 1111 is added to the base pointer, yielding a sixteen
# bit value of 0000 1001 1111 1111 for the UCS2 character
# (i.e. '09FF').
