[I18n-sig] Strawman Proposal (2): Encoding attributes

I think the proposal was to do

3. raise an error if another literal uses bytes > 127

instead. Since users need to actively change their source to use the
encoding declaration, they'll combine this with putting u in front of
every affected string. If they then still have strings with bytes
>127, they need to use the \x notation, as the string should not
contain text.
