> Currently, LDAP ASN.1 decoder transforms byte[] to String via calls such as:
>   String any = new String( tlv.getValue().getData() );
>   (source: /ldap/src/main/java/org/apache/directory/shared/ldap/codec/actions/StoreAnyAction.java,
line 74)
> This uses some default encoding, though according to LDAP RFC, UTF-8 should always be
used (http://www.rfc-editor.org/rfc/rfc2251.txt, section 4.1.2).
> I recommend that the following code be used for converting byte[] to String:
>   // static variable containing the UTF8 encoder
>   private static final Charset UTF8 = Charset.forName("UTF8");
>   // wherever byte[]->string conversion is needed
>   String any = UTF8.decode(tlv.getValue().getData()).toString();
> From user's perspective, the problem is that non-ASCII characters in search filters are
messed up, and search doesn't return any results.
