I found that some characters are displayed with a one character size where it should have a two character size, for example: ⛩ U+26E9 ⛰ U+26F0 ♬ U+266C ⛚ U+26DA
⛩ (U+26E9) and ⛰ (U+26F0) are classified as emoji [1] and should be rendered as wide [2]. ♬ (U+266C) and ⛚ (U+26DA) are not emoji [1] and their East Asian Width is ambiguous [3]. Ambiguous width characters should be rendered as narrow when the context cannot be established [2]. The ambiguous/non-emoji characters width should not be changed by default, but adding an option for user to decide would be nice.

> The ambiguous/non-emoji characters width should not be changed by default, but adding an option for user to decide would be nice. This would be great, because not all shell agree with that value, and the terminal emulator and the shell not agreeing on the size of characters results in buggy behavior.
This is still not fixed despite that «Konsole now fully supports emoji characters». Any news on this? https://www.kde.org/announcements/announce-applications-18.12.0.php
When writing comment #1 I did a mistake and didn't check all information about ⛩ and ⛰. They are ambiguous with undefined width. However, this is a part of bigger problem with ambiguous characters and glyph width - marking as duplicate to keep things organized *** This bug has been marked as a duplicate of bug 401298 ***
