explicitly list the number of bits used for red, green and
blue components as a slash-separated list of decimal integers.

+ Because there are several RGB encodings in use, applications

drawing characters, and that it should ignore the alternate char-
acter set capabilities when the locale uses UTF-8 encoding. For
