Interesting proposal. I really like it indeed. I wonder how people
against "magic" will like it. Although there is a precedent with the
first line giving the path to the interpreter.
.. but it sounds quite a fair proposal and would solve some of the
issues raised here before
But i wonder if you would see the security issue with some person
sending you diff file that would (among other changes...) do
something like this
(inserted a blank line)
Then you would be in trouble again...
An alternative would be to require for any comment before any code
that purposes to set identifier encoding restrictions etc... to be
preceded by a specific character (just like the unix convention with
the " ! "). Any comment line starting with this character would be
restricted to be ascii only. "%" sounds like a good character for this
Like for example...
# %coding: utf-8
# %identifier_charset: 0-1fffff
# %string_charset: 0-1fffff
# %indentation: unmixed
