I agree: since short tags remain valid syntax, the parser and tooling
must correctly handle them in all configuration states.
Therefore, I propose replacing `<?~ ... ?>` with `<?: ... ?>`.

everyone uses UTF-8, East Asia specifically. Introducing a core syntax
and excluding a huge portion of users is not a good move.
The semantics of `<?: $expr ?>` would be equivalent to: `<?php echo
htmlspecialchars($expr, ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML5); ?>` --
that is, the encoding will be determined automatically via the current
default_charset setting, as htmlspecialchars() does by default.
Best regards,
