Unicode is about plain text. TeX is about fine typesetting.
There's no reason why TeX should typeset ASCII as upright, any more
than it should typeset "\begin{section}" as that literal string! The
use of ASCII characters in math mode is simply an input convention, to
indicate the desired output of italic letters in a style appropriate
for single-letter mathematical variables.
The use of other Unicode characters in TeX input files is also simply
an input convention; how they get typeset depends on many other things
than what they look like in the code charts.
