That is inherently non-portable. POSIX states that "Other characters may
be permitted by an implementation; applications shall tolerate the
presence of such names," but does not require applications to be able to
create such names.

You'll have to set it in Windows, prior to starting bash, as there is no
way to make bash create variables not starting with something from the
portable set [_a-zA-Z].
This behavior (accepting names of only ASCII Alpha and _) is a bash self
imposed limitation. If you use csh (or tcsh) names with other characters
are supported too.
So you can use csh's: setenv "@FOO" "value".
You can also use the env command to bypass bash limitation like this:
exec env "@FOO=bar" exec /bin/bash -i
Note the 2 `exec' if you do not want to spawn more processes.
