I don't think it is possible to have a Unix user with a username that contains non-ascii characters, sorry. Too many tools will fail, and it has the potential to confuse file formats like /etc/passwd.

is it possible to create unix user account using ascii than add utf8 email address by coding the source file?

if it's possible please let me know which file to change to.

thanks

Can an email address actually contain non-ascii characters? Or are you using some ascii encoding of UTF-8 for use in addresses?

https://en.wikipedia.org/wiki/Email_address

Internationalization

"The IETF's EAI Working group published RFC 6530 "Overview and Framework for Internationalized Email", which enabled non-ASCII characters to be used in both the local and domain parts of an email address. RFC 6530 provides for email based on the UTF-8 encoding, which permits the full repertoire of Unicode. RFC 6531 provides a mechanism for SMTP servers to negotiate transmission of the SMTPUTF8 content."

Internationalization examples

These addresses are not compliant with RFC 5322 and will therefore not work with many of the current generation of email servers and clients. RFC 6530 compliant servers should be able to handle these.

Latin Alphabet (with diacritics): Pelé@example.com
Greek Alphabet: δοκιμή@παράδειγμα.δοκιμή
Japanese Characters: 甲斐@黒川.日本
Cyrillic Characters: чебурашка@ящик-с-апельсинами.рф

That seems to support what I wrote - that most mail servers won't accept non-ascii addresses.
