UTF8 char U+26A1 is displayed as a 2-width character

[Thomas]

I have noticed that Sakura is having problems displaying U+26A1 - ⚡.
It is too wide (looks like 2 characters) and so it messes up my prompt.

I am using Sakura 3.3.4, zsh5.2 and latest and greatest oh-my-zsh (OMZ) with the Agnoster theme
(https://gist.github.com/agnoster/3712874)

The second-to-last line is a root-prompt and there are problem with that ⚡. If the prompt is empty the curser is kinda just after the > powerline sign, with no space in between.
After I typed something and want to auto-complete all shifts right and messes up what I typed, as it looses the most right character.

I submitted a bug report to OMZ here: https://github.com/robbyrussell/oh-my-zsh/issues/5546#issuecomment-254788705 but it appears to me this is more a terminal issue than an issue with zsh/omz.

With bash it doesn't show up any of the problems you mention, so i'm guessing is a problem related to zsh and/or OMZ.

If I start a bash session inside my regular Sakura window (ie. no powerline, no zsh and no OMZ) I won't have the pretty prompt anymore,
but inserting ⚡ is showing the same problem, it is displayed as a 2 character wide character.

I run some check and the system is has stored it as a 1 character wide, other UTF8 are also 1 character wide, only this one it seems is 2 character wide.

It *looks* to me like a problem with Sakura. I understand it necessarily doesn't have to be, it could be a character set issue, font issue, X issue ... whatnot. If you point me in the right direction I am more than happy to raise this issue elsewhere.

zsh-5.2, Schutzstaffel (⚡⚡) displayed correctly. Current font is Consolas Regular 10.

I'll mark this bug as closed. Please open it again if you can reproduce it with a system with an installed glibc version >= 2.26.
