This turned out to be more interesting than I thought. https://www.w3.org/International/questions/qa-controls says that (most) control characters are invalid in the context of HTML 4, and can only be represented as &#-sequences in XML 1.1; however, Qt's own QTextDocument happily exports text without (at least) turning \x1b characters to &#27. Seems like incompliance on Qt side.

KitsuneRal commented

Also, ftr: the crash is actually an assertion failure; if you build in Release configuration, you just won't be able to send a message with control characters, so it's not too grave.

mizhka commented

@KitsuneRal : title has been corrected (crash->assert).
QT bug: fingers crossed, but do you plan any action in addition?

KitsuneRal commented

I can try to insert some workaround, perhaps... I already have a few, anyway.
