[Hatuka*nezumi - IKEDA Soji]

Hi.

These patches are against 4.0.4.20040524 (or later).

sqwebmail-cvs20040528-mimeheader.patch
  rfc822/rfc2047u.c
  - New functions:
      rfc2047_encode_unicode()
      rfc2047_encode_str_fromutf8()
      rfc2047_encode_header_fromutf8()
    They are Unicode version of rfc2047_encode_str() and rfc2047_encodeheader().

sqwebmail-cvs20040528-utf8pref.patch [depends on above]
  sqwebmail/*
  - Read/write following files using UTF-8 so that configurations 
    are charset independent:
      MAILDIR/sqwebmail-addressbook
      MAILDIR/sqwebmail-config
      MAILDIR/sqwebmail-ldapaddressbook
      MAILDIR/sqwebmail-sig
      SYSCONFDIR/ldapaddressbook
  - pref_from, pref_ldap and login_fromhdr() now returns UTF-8 
    value.

  NOTE: Convert/update last 3 files to UTF-8 (if needed).
    sqwebmail-addressbook and sqwebmail-config will be updated
    automatically.

sqwebmail-cvs20040528-sqwebmail.patch [independent]
  - All shown headers will be decoded.
  - Some bug fixes.
