[issue25182] python -v crashes in nonencodable directory

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

python without -v is not failed.

If wrap message in _bootstrap_external._verbose_message with '!%a'% and in _bootstrap._verbose_message with '%a'% (why _verbose_message is duplicated in _bootstrap and _bootstrap_external?), the output is:

Verbose non-ascii message is written before importing codecs.
