It could be. (It probably should be.) Also, given the custom reader
ability of the framework,

#lang text/plain;charset=utf-8

would be, while

#lang text/plain;charset=iso-8859-15

would not be. (How handy that ; is a comment character in the bootstrap
reader!)

Aw, rats, I just tried that last example, and it doesn't work:

tt.rkt:1:0: read: expected only alphanumeric, `-', `+', `_', or `/'
characters for `#lang', found ;
