Improperly - but quite common, at least here in Germany. RFC2459 also says 
that a TeletexString should be interpreted as Latin1:
  In addition, many legacy implementations support names encoded in the
  ISO 8859-1 character set (Latin1String) but tag them as
  TeletexString.  The Latin1String includes characters used in Western
  European countries which are not part of the TeletexString charcter
  set.  Implementations that process TeletexString SHOULD be prepared
  to handle the entire ISO 8859-1 character set.[ISO 8859-1]

Is there already a function like ldap_t61s_to_utf8s for latin1? 
Implementing it shouldn't be much work since each code point in Latin1 is 
the same in Unicode.
