There are two operations:
1. Concatenating the strings.
2. Invoking write().
First step I would make is to find out which of the two is raising the
exception. Anyway, it probably is the second one, i.e. the call to write().
What is happening there is that the file's codec is trying to convert the
Unicode string to bytes for the configured encoding ('ascii') but fails
because there is no representation for u'\x93' there (Note: ASCII only uses
the byte values from 0 to 126, the above is 147).
The remedy is to set the output encoding to e.g. UTF-8 (default for XML) or
ISO8859-1 (default for HTML) or whichever encoding you want. Otherwise,
just throw the error message at the search engine of your least distrust to
find a bazillion of other users that had similar problems. ;)
