In my case, when I open certain files in
tmux such as this file, and have multiple panes, the characters overflow the pane's boundaries.
Nicholas Marriott suggested that the
terminal versions of Unicode could be differing from one another:
ldd --version, I have verified that I am running 2.23 which seems to support Unicode v8.0.
Because, I couldn't easily find out the Unicode version of the font, I was using
Consolas, I instead tried a number of other fonts such as the latest version of
Anonymous Pro, Source Code Pro, Lucida Console to exceed or match the version of Unicode supported by my
glibc (assuming Unicode versions would be backward compatible). However that didn't help.
Further, I have tried using professionally supported version of ssh terminals such as
bitvise ssh client.. But none of these helped. So I am back to the original question of figuring out what unicode version is supported by my terminal (Putty), and the font I use (Consolas).
How do I check what version of Unicode I have running for the font of my terminal, and the terminal itself?
