I saw youe example page. this was true in "Firefox 2.0.0.12" and "Internet Explorer 7.0" Please note that Mmany of Iranian users, uses "Internet Explorer 6.0" and "Windows XP Pro" operating system.
Could you try the attached patch with the current svn, send a message with Persian (or other rtl) text, and check if it displays properly in the web mailer and the other mail apps you use?
The patch replaces the current text/plain with a text/html and (hopefully) includes the proper rtl and ltr tags. It does *not* yet encode highlighting and hyperlinks, and it does *not* create the multipart/alternative as indicated yesterday. This is simply a _very_ dumb check whether it is possible to compose a "proper" message in html, so the "real" code would be some further effort. I unfortunately cannot test it here, so if you can confirm that this way Balsa would work for the Persian community (and probably the Arab and Hebrew, too), it would /really/ be helpful!
Thanks, Albrecht.
