| Subject: | use utf8 causes encoding issues |
When using unicode characters in Email::MIME the result from as_string()
is sometimes double encoded utf-8.
In the attached test script this behaviour is triggered by having a use
utf8 to correctly interpret the inline utf8 strings. Normal output from
as_string() can be triggered by including the no utf8 clause (commented
out).
Imho the main problem is that Email::MIME is joining byte strings (when
creating a message to be sent) and depending on the context (e.g. use
utf8) will have those strings interpreted as utf-8 strings. This will
result in the bytes being encoded twice (as seen in the test script).
