Issues with double-width chars

[svvac]

(found #228 and #238 that look related-ish but havent seen these specific problems reported)

When the first glyph on a line is a double-width glyph, the whole line is displayed scaled down :

$ printf "✖ 1 problem\n ✖ 1 problem\n"
✖ 1 problem
 ✖ 1 problem

Executing the printf above yields :

Additionally :

• This also occurs when the cursor is at the last position before a double-width glyph:
• The cursor does not match what is underneath:
  • here, visually above the space, but displays 1 when the cursor is there:
  • here, the cursor is at the end of input:
  • generally, mouse selection is way off when there are double-width chars

Hey @svvac thanks for the issue,

I cannot reproduce the first part, but I assume is a font issue (not your font but Rio isn't dealing well with it).

The second problem, I can reproduce.

For repro, the font is a patched Iosevka from nerd fonts.

@svvac would mind sharing more information on your environment?

Tried to reproduce this with the given font above, and it seems to be working normally for me. I am using SLES 15 SP6, and rio version 0.0.34 with the Iosevka font

I'm on Arch if this matters. If you need more versions, please ask.

$ rio --version rioterm 0.0.33

you aren't using the latest version of rio. Try, updating your system or build from the main branch.

[svvac]

Well it was the latest at the time I filed this ticket.

Now it says rioterm 0.0.34 and the issue is still present.

[raphamorim]

This issue should not be able to reproduce with the latest release (v0.1.0), closing this issue for now. In case find anything odd please let me know and we can reopen or create a new issue.
