If both PuTTY and server side charset are set to ISO-8859-15 window title disappears at login and is empty no matter what. Propably has something to do with issue 88 since title is visible if charset is UTF-8. Works correctly in previous version p0.63-t017.
So this is 6fd9b21 / GH-88. I couldn't actually find any common usecases where this broke, but if people are hitting it then I will actually have another attempt.
I confirm this bug. I am able to get the title back if I minimize the window to tray and restore it back. Also when going to Change settings and just clicking Apply does the trick (the correct title is visible in the settings/window/behaviour). The bug doesn't need high-ascii latin1 characters to be repeated, just changing it in bash by echo -ne "\033]0;abc\007" makes the title dissappear again.
Revert "GH-88", as it breaks some people (GH-109)
