Emmanuel Lecharny commented on DIRSTUDIO-963:
---------------------------------------------
I confirm this is a bug.
o create a new entry
o select 'person' as an ObjectClass
o add a 'cn' which value is 'Lécharny'
o the DN is converted to a String representation of the RDN, where the 'é' is
escaped : cn=L\C3\A9charny,ou=system
This conversion should never occur at this point. RFC 4514 is pretty clear
about that :
distinguishedName = [ relativeDistinguishedName *( COMMA
relativeDistinguishedName ) ]
relativeDistinguishedName = attributeTypeAndValue*( PLUS attributeTypeAndValue )
attributeTypeAndValue = attributeType EQUALS attributeValue
attributeValue = string / hexstring
string = [ ( leadchar / pair ) [ *( stringchar / pair )( trailchar / pair ) ]
]
leadchar = LUTF1 / UTFMB
stringchar = SUTF1 / UTFMB
trailchar = TUTF1 / UTFMB
and from RFC 4512 :
UTFMB = UTF2 / UTF3 / UTF4
UTF2 = %xC2-DF UTF0
UTF3 = %xE0 %xA0-BF UTF0 | %xE1-EC 2(UTF0) | %xED %x80-9F UTF0 | %xEE-EF
2(UTF0)
UTF4 = %xF0 %x90-BF 2(UTF0) | %xF1-F3 3(UTF0) | %xF4 %x80-8F 2(UTF0)
UTF0 = %x80-BF
> Why UTF-8 is escaped in DN strings since 2.0.0?

> Key: DIRSTUDIO-963
> URL: https://issues.apache.org/jira/browse/DIRSTUDIO-963
> Project: Directory Studio
> Issue Type: Question
> Components: studio-ldifeditor
> Affects Versions: 2.0.0-M8 (2.0.0.v20130628)
> Reporter: Dmitri Chubarov
> Labels: newbie
> Attachments: Screenshot-Rename Entry - 1.5.3.png, Screenshot-Rename
> Entry - 2.0.0-M8.png
>
>
> I have a directory that includes many DNs containing UTF-8 characters. I
> expect the characters to be displayed correctly in the LDAP browser tree. The
> server claims to support LDAP v3.
> Recently I installed Apache Directory Studio 2.0.0-M8 and realized that new
> entries created with the Directory Studio have UTF-8 characters escaped when
> a DN is created, e.g. "TESTСкаж...,dc=ru" is replaced with
> "TEST\D0\A1\D0\BA\D0\B0\D0\B6...,dc=ru".
> Since escaped secuences make the tree illegible in the LDAP Browser I had to
> manualy rename new entries using ldapmodrdn utility from OpenLDAP
> distribution.
> I have tested few prior versions of Apache Directory Studio. Here is a
> summary of the results:
> 1.5.3 - entries created with UTF-8 characters in DN as expected.
> 2.0.0-M3 - the Directory fails to load with ArrayIndexOutOfBounds exceptions
> 2.0.0-M7, 2.0.0-M8 when DN is formed by the Directory Studio all UTF-8
> characters are escaped.
> Is this an expected behaviour or is this a regression? If this behaviour is
> expected is there a way to get UTF-8 characters back into the DNs?
