使用Java Mail API发送电子邮件时出现编码问题

Question

I am sending email using java mail api in my application. The subject of email contains hyphen( - ) character. This works fine on windows machine. But once I deploy the application on linux machine, the recipients of email get emails with hyphen getting converted into question mark in the subject of emails.

This problem is occurring in Cent OS linux environment. This is working fine with windows and ubuntu linux environment.

Can somebody please suggest what could be the problem?

Thanks.

Are you sure the hyphen character is actually the regular ASCII hyphen (0x2D)? If it's something that looks like a hyphen, but is actually a Unicode character from a different language set, you could easily see encoding problems across environments.
