tSendMail - encoding not applied to subject and sender

Issue:

tSendMail allows you to set the encoding, but it appears that this encoding setting only applies to the message.

Looking at tSendMail_main.javajet, the "<%=encoding %>" setting is not applied to the subject.

subject
msg_<%=cid %>.setSubject(subject_<%=cid %>);

message
mbpText_<%=cid %>.setText(message_<%=cid %>,<%=encoding %>, "<%=mimesubtype %>");
mp_<%=cid %>.addBodyPart(mbpText_<%=cid %>);

How can the encoding be applied to the subject ?

Solution:

The "<%=encoding %>" setting is not in the code for subject and this was reported in Talend Defect/Enhancement incident system as:

TDI-18853: When use tSendMail, "encoding" of Advanced setting isn't reflected to Subject and Sender's name.

The issue has not been addressed but the following workaround can be used:

Add to the startup (ini / bat file) when launching JETL Studio. 

-Dfile.encoding=UTF-8
