HelpMenu: non-ascii characters insert extra spaces

[bbjubjub2494]

On the help screen, gotop typesets characters based on their byte length in UTF-8. This causes weird spacing in most languages that aren't English. This can be seen in German (lö schen, wä hrend), Esperanto (paĝ o) and upcoming French (dé but, entiè re) In Chinese this causes extra spacing between all ideographic characters. The main screen is not affected.

Termui has a Paragraph widget that can handle i18n typesetting better than the ad-hoc loop from 3 years ago. I'm working on it in b24c384. It typesets but the window is sized in such a way that it sometimes eats the last line so I need to fix that.

gotop version:

gotop v4.1.1 (Hadean)

(not fixed in master afaict)

OS/Arch:

4.19.118 GNU/Linux (NixOS)

Terminal emulator:

Sakura

tmux version:

Also please copy or attach ~/.local/state/gotop/errors.log if it exists and contains logs: [empty]

@lourkeur outstanding report; thanks for all of the information.

@lourkeur Thanks for the work on this. When do you see it eating the last line?

I'm pushing my version of your changes into master; the Paragraph struct seems to work well for all languages I've tried it with. Can you see if you can reproduce the issue you were seeing with that code?

@xxxserxxx Your candidate is good to go as far as eating the last line goes. The textHeight calculation needed to be adjusted by 1. Your patch did, mine didn't. That's language independent as well.

Thanks; your code was helpful for getting it done quickly. Closing.
