Emoji characters cause lingering ghost characters when screen updates
Opened this issue · 1 comments
I run WeeChat 1.9 on a remote server and connect to it by SSH. Occasionally people send the Unicode emoji characters into IRC, and I've noticed that PuTTYTray has problems displaying these:
When swapping between WeeChat windows, when the window being swapped into has an emoji in it, some characters from the previous window stick around next to the emoji character, instead of fully refreshing like they should. See the picture above for what I mean, it's PuTTYTray and PuTTY 0.70 displaying the same tmux session of WeeChat. The bug manifests itself on the left in PuTTYTray, the cyan 7 is leftover from another WeeChat window and should not be there.
This doesn't happen with PuTTY 0.70 or any Linux terminal emulator I've tried, so I think it's a problem with PuTTYTray rather than server-side in WeeChat.
I get this all the time with server side weechat in gnome-terminal.
This is unlikely to be a PuTTYTray specific issue, and sounds like it will be fixed by the upgrade of the back-end to 0.70.
