command-line options for "Content-Transfer-Encoding: quoted-printable"

[GoogleCodeExporter]

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!

It turned out that the problem is not the encoding rather problem with reading 
multibyte characters from windows command line. mailsend uses standard C 
functions and does not have support for multibyte input from windows command 
line. I tested from Linux using gmail SMTP and the message was correct even 
without any encoding (just needed to specify charset to Big5). I will add the 
support for multibyte characters for -M option in windows but it will take some 
time.

Thanks.

The option -enc base64 is available in v1.17b13. However multibyte character 
input in windows still remain, I just do not have time to change all the string 
related functions to handle multibyte input. So the new option is only useful 
in Linux and Mac.
