UnicodeDecodeError: 'ascii' codec can't decode byte 0x8c in position 14: ordinal not in range(128)

[lukasz.matecki@…]

I can see that this is related to the Polish locale, the unicode error occured at the local time designation "X-WR-TIMEZONE:\x8crodkowoeuropejski czas…" where \x8c stands for Polish "ś".

How to Reproduce

While doing a GET operation on /roadmap, Trac issued an internal error.
