* *idpattern* -- This is the regular expression describing the pattern for
non-braced placeholders. The default value is the regular expression

``None`` this pattern will also apply to braced placeholders.
.. note::
Since default *flags* is ``re.IGNORECASE``, pattern ``[a-z]`` can match
with some non-ASCII characters. That's why we use the local ``a`` flag

- ranges is redundant, but required for backward compatibility.

- While *flags* is kept to ``re.IGNORECASE`` for backward compatibility,
- you can override it to ``0`` or ``re.IGNORECASE | re.ASCII`` when
