What steps will reproduce the problem? mailsend -smtp smtp.gmail.com -port 465 -ssl -v -auth -user someone -pass something -f someone@gmail.com -t someother@gmail.com -cs Big5 -sub "text in chinese test" -M "text in chinese test 中文測試" What is the expected output? What do you see instead? "中文測試" is the meaning of "text in chinese test"
It should display the correct words.
However I got the worng code as "銝剜?皜祈岫" What version of the product are you using? On what operating system? mailsend1.17b12.exe Windows XP in Big5 Chinese Please provide any additional information below. I guess it would be someting wrong in the path which that passing the double word charset.

So, I sent the mail by mailsend and using gmail to send it again.
To check the difference.

sent by mailsend :

Content-Type: text/plain; charset=Big5
Content-Disposition: inline

text in chinese test 銝剜?皜祈岫

sent by gmail :

Content-Type: text/plain; charset=Big5
Content-Transfer-Encoding: quoted-printable

Chinese text testing
=A4=A4=A4=E5=B4=FA=B8=D5

The key difference is "Content-Transfer-Encoding: quoted-printable".
So, I have a suggestion.
Can you provide the command-line options for user for assign the Encoding about "quoted-printable" ?
If it can be, your program can send any kind of word for gmail system without any problem!

Thank you!
