Konsole vs Sakura wide font rendering.

Every modern terminal I test (sakura, st, xterm, gnome, termite) is able to
render wide fonts correctly. I really don't understand why Konsole is unable to
do the same since forever.

STEPS TO REPRODUCE
1. Configure some nice fonts with powerline glyphs (e.g. fira code)
2. Render them in konsole (see attached script).


OBSERVED RESULT

Half of each font is rendered.
Highlight with mouse to copy any of the fonts is nearly impossible.

EXPECTED RESULT

Fonts should be fully rendered as in any other terminal (see attached
screenshot).

Selecting and copying with the mouse should work as with any other text.

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: NEON latest updates.


ADDITIONAL INFORMATION

At some point in time fonts were rendered correctly when disabling
bi-directional text rendering in Konsole settings. Cannot remember which
version.
