[fanthos]

Possible related with #1083 . Unicode CJK seems fixed, but some other chars not work as excepted. ➜ is an example that not working correctly in ConEmu.

Versions

ConEmu build: 171109 x64 OS version: Windows 10 1709 x64 Used shell version (Far Manager, git-bash, cmd, powershell, cygwin, whatever): mintty, bash

Problem description

Steps to reproduce

1. Install WSL on Windows 10
2. Install Zsh and Oh-My-Zsh
3. Start Zsh

Actual results

I see bad alignment in "Windows Bash console". ConEmu shows same alignment as mintty.

[fanthos]

The cursor is not in the right position. In windows console and mintty, when I am typing, the cursor is just at the position char appear.

[fanthos]

ConEmu not shows same as mintty, the symbol is a little wider than normal chars, and cursor is not at right position.

Have you seen this? https://conemu.github.io/blog/2017/11/17/Build-171117.html

the symbol is a little wider than normal chars

If the font you are using draws the glyph using this width, what ConEmu can do?

[fanthos]

After upgraded to 171117, the issue still exists. The cursor should display at the position new char appears. I think when calculating the cursor position, it considered ➜ as 2 chars width, but when drawing it does not calculated as 2 chars width. The following is screenshot shows the align problem, I typed _ without the following whitespace.

[fanthos]

The character should consider as 1 wide char in both drawing and cursor, or 2 wide for both.

Not fixed

[Maximus5]

On your screenshot I see gaps between _ _ _. If you didn't enter spaces that means that _ is shorter than a cell and gap between _ and the cursor is expected.

[fanthos]

I have space input between _s and it works as excepted. The problem is with ➜. The cursor moves 2 cells but text moves about 1.2 cells.

Copy and paste ➜ to come up can easily reproduce the issue.

Tested on bash and cmd, both have the issue.

Running to this issue as well; it's a bit easier to see the misalignment if you start tmux and split the pane:

ConEmu:

mintty:

You can also see this just by running tmux + sh and doing echo ➜:

ConEmu:

mintty:

This is with ConEmu build 180506 (x64), Windows 10 1709 (x64).

Problem remains in 191012 x64/x86, Win10 1909 x64. Qoute mark in gcc output is causing problem. Using default settings and fonts for ConEmu. Plus it's okay with mintty.
