Characters not forming part of the initial set in the character box beneath the colour palette
encode to, assuming UTF-8, 2-3 bytes in total vs. one (1) byte for those part of the initial
set (e.g. 0-9, A-Z, a-z, etc.)
Internet Explorer is explicitly unsupported.
Repeating patterns of alternating back- and foreground colours, and vice versa, are encoded
using a single (1) byte in mIRC format (video reverse) and as such save space, especially
with large numbers of repetitions or alternations.
