During the import process, your biblio records are converted into UTF-8
encoding. That's the reason why 01 is transformed into 50. This is
required.  Otherwise, biblio records parsing inside Koha would fail. The
transformation of 'ita' into 'fre' is not required. Koha could be
modified to leave this 100 tag part unchanged. Take a look at
C4/Charset.pm module: if you fix that you should submit a patch to the
community. For tag length truncation, I have no idea...
