Bug#961675: reportbug: Cannot report bug due to char encoding problem

[Marc-Jano Knopp <pub_br_debian.org@marc-jano.de>]

Package: reportbug
Version: 7.6.0
Severity: normal

Dear Maintainer,

today I tried provide extra information for an existing bug report,
which failed:


$ reportbug -N 590876
Warning: untranslated token "envelopefrom"

Retrieving report #590876 from Debian bug tracking system...

{ Here, I get a "less" prompt reading "byte 0/0 (END)", which I quit by
  pressing 'q'. }

Traceback (most recent call last):
  File "/usr/bin/reportbug", line 2284, in <module>

  File "/usr/lib/python3.8/encodings/iso8859_15.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode character '\u0148' in position 369: character maps to <undefined>
$ echo $?
1
$

Observations:

- The error does not occur with an UTF-8 uxrvt.
- The error does not occur on e.g. bug #177000.
- It seems it chokes on the name of the "Upstream Author" in #590876.
- It may be that bug #814454 is related to this bug.
