I don't know what Window does -- some programs want to treat Ctrl-I as
other than Tab, Ctrl-M as other than Enter, etc. -- but Vim simply
follows what was set long ago by ASCII (at a time when 7 bits were
thought to be enough for a character and anything happening outside the
borders of the 50 states, and also anything in non-English languages
including Spanish, Yiddish, Cajun and Cherokee, could just as well have
been in outer space), and it leaves, among others, Ctrl+0x20 to
Ctrl+0x3F "undefined".

And yes, Ctrl+Alt+@ is 0x80, Ctrl+Alt+A is 0x81, etc. (in UTF-8 or
Latin1, these 32 characters, 0x80 to 0x9F, are all rarely used
non-printing control characters; in Latin9 aka ISO-8859-15 and in
Windows-1252 some or all of these byte values were attributed to
characters nonexistent in Latin1, and above U+00FF in Unicode, such as
the Euro sign, the French oe and OE digraphs, etc.).
