I am writing to ask for suggestions in bug Issue #21538 in php-src [1].
Currently when zend.multibyte=0, declare(encoding=...) will emit a
warning for whatever the encoding is:
[…]
This would be a very minor change and do not worth a separate RFC.
However, I think it is still important to send a email to gather
opinions :) Also thank @alexdowad for giving me ideas. TiA :)
I suppose that `declare(encoding=…)` is so rarely used that folks will
not have a strong opinion on it either way - except possible to remove
the feature entirely to keep the parser simpler. That said: Suppressing
the warning for ASCII and UTF-8 makes sense to me if folks want to
explicitly specify it for some reason and zend.multibyte indeed has no
effect at all on those encodings.
