* we are assuming. If we wanted to accomodate these servers we could
* translate the data when we use it. LDAP data is only used in a few
* places so it might not be too hard to fix it. There are four calls
* into the LDAP library that produce character strings which are
* supposed to be UTF-8. They are
* ldap_get_dn
* ldap_first_attribute
* ldap_next_attribute
* ldap_get_values_len
* We call those from a half dozen functions. We could fix it by
* having a directory-character-set per server and passing that around
* in the LDAP_SERV_RES_S structure, I think. For now, let's go with
* the assumption that everything is already UTF-8.
