Special Characters in X 509 Certificates

[özgür berksoy]

Hi,

I've actually 2 problems.

First is:

    Is it possible to create a X 509 certificate with 'µ' character inside
the subject alternative name ?
    When I try to run following command :

         openssl req -new -x509 -nodes -sha1 -extensions v3_ua -keyout
µBOX_3.Cert.pem -outform DER -out µBOX_3.Cert.der -days 10950 -config
cert.cnf

    with

        subjectAltName=URI:http://µBOX_3:8080 <http://xn--box_3:8080-iph>
,DNS:µBOX_3

    entry inside the cnf file, I get an error:

        problems making Certificate Request
        1188:error:0D07A07C:asn1 encoding
routines:ASN1_mbstring_ncopy:illegal characters:.\crypto\asn1\a_mbstr.c:162:

    When I additionally use -utf8 parameter, I get a similar error:

        problems making Certificate Request
        2868:error:0D07A086:asn1 encoding
routines:ASN1_mbstring_ncopy:invalid utf8string:.\crypto\asn1\a_mbstr.c:132:

Second problem is:

    Is it possible to use the same 'µ' character with:

        -subj /DC=µBOX_3

    addition to the command ? When I try to do it I get the same errors in
the first problem.

I'd appreciate any comments.

Thanks..
