We noticed that when we ran a webinar and a participant asked a question in the Polish language - then the field where he wrote the question is cleared. Everything that he wrote is deleted once he uses a letter that is in the Polish alphabet (like ż, ź, ć, ś, ó, ł, ą, ę). That appears also for an organizer who writes a response. That is quite annoying as sometimes you spend some time writing a question or answer and you lose your effort. Those letters are compliant with ASCII, Window-1250, and ISO-8859. That was the first such situation working with marketing and IT systems when I saw that software behaves like that.
