Bug#873674: libdazzle: FTBFS: 'ascii' codec can't decode byte 0xe2

[Aaron M. Ucko]

Source: libdazzle
Version: 3.25.5-1
Severity: serious
Justification: fails to build from source

Builds of libdazzle under the traditional C locale (as on the
autobuilders, implicitly) have been failing as detailed below.  Please
try arranging for debian/rules to export LC_ALL=C.UTF-8, which should
be available by default (via libc-bin) these days.

Thanks!
