A last missing link for interoperable representation

[James Kass via Unicode]

Reading & writing & 'rithmatick...

This is a math formula:
a + b = b + a
... where the estimable "mathematician" used Latin letters from ASCII as 
though they were math alphanumerics variables.

This is an italicized word:
������������������������
... where the "geek" hacker used Latin italics letters from the math 
alphanumeric range as though they were Latin italics letters.

Where's the harm?

FWIW, the math formula:
a + b # �� + ��
... becomes invalid if normalized NFKD/NFKC.  (Or if copy/pasted from an 
HTML page using marked-up ASCII into a plain-text editor.)

Yet the italicized word "kakistocracy" is still legible if normalized.  
If copy/pasted from an HTML page using the math alphanumeric characters, 
it survives intact.  If copy/pasted from markupped ASCII, it's still 
legible.
