My requirement is statename, countryname, CommonName should be in language other than English. e.g. Chinese . Is it possible to create such certificate?

It is possible to create OpenSSL certificate with non-ASCII characters by using the -utf8 option.

In order to get a certificate for a public key, you create a Certificate Signing Request (CSR) that contains the information to be certified, such as the Distinguished Name and Common Name, Organization, City, State, Country and Contact information.

When creating a CSR, OpenSSL interprets any text you enter as ASCII. If you try to enter non-ASCII characters (such as Chinese), the certificate will contain 'random' characters rather than the text you tried to enter.

However, it is possible to change this behaviour using the -utf8 option (see OpenSSL Wiki):

openssl req -new -utf8 -newkey rsa:2048 -sha256 -out csr.pem

In this case, the information entered is interpreted as UTF8, allowing you to enter Chinese characters in the interactive dialog asking for the Common Name, State, City, etc.
