OK for UC-only poor devices, but quality typeset is supposed to keep
some lower case letters even in "all caps" -- such as, f.i., the "c" or
"ac" of scottish names starting with "Mac", or SI preffixes. Note that
"m" stands for milli (10E-3) while "M" for "mega" (10E6), an essential
difference -- and the recently adopted preffixes for >|21| magnitudes
use precisely case to mark the signum difference (q.v. -- cannot check
right now).
(Anyway, the above "10E6", brings back the topic of letters as numbers:
hexadecimal notation and >9 hack digit symbols, roman numerals, and this
weird U+0045 standing for U+00D7 U+0031 U+0030 <sup>...)
