mIRC 6.17 has a text wrapping bug when utf8 is turned on to "display" (or display and encode) in a channel that uses certain fonts, where it seems to wrap the text regardless of whether the wrap breaks up a character consisting of two or more bytes.

As example, the following screenshot using the japanese enabled fixedsys on windows XP (the only difference between the lines is the number of leading ascii spaces): http://www.nihongoresources.com/downloads/mircgarble.PNG

Resizing mIRC or the channel window will make garbled sentences legible but will then of course wrap certain long sentence that showed fine before incorrectly.

It is uncertain whether this bug has anything to do with the width of the font being fixed or not, as MS UI Gothic also has this problem but Courier does not, for instance.

confirm bug?
