Since my last answer, I wonder how it is possible to get non ASCII
characters from these files. Did you manuallly edit a local cache file
at some point?

Please, show us the head of your LocalStatus files. They stands in the
cache. Look for the Account-<name> with the name of the offending

  % cd <cache path>/Account-<name>/Localstatus
  % file *
  % head -v -n1 *

Report the results of the last two commands.
