Missing characters (urxvt issue)

[Riiskyy]

Hi, so I installed this and the ncurses5 library from the AUR. However my terminal does not display any of the special characters

I'm running a patched nerd font with the ncurses5 compat libs from AUR

[M4444]

I'd like to rule out the option that either the font or the terminal you're using doesn't fully support unicode. If you copy this ﾏﾄﾘｯｸｽ into your terminal or cat this document does it print it correctly?

[Riiskyy]

I can copy and paste those symbols to the terminal fine. Cat-ing that document everything dislpays correctly except the ethiopian and Runes secions. I'm using Urxvt as my terminal emulator if that helps

[M4444]

Can you send me the output of compiling and running this: https://www.dropbox.com/s/v2k19a19z2kn7vz/size_test.cpp?dl=0?

tom@home ~ $ g++ Documents/test.cpp -o Documents/test1
tom@home ~ $ cd Documents/
tom@home ~/Documents $ ./test1

I think I ran this all correctly?

[M4444]

Yup that checks out, thanks. Maybe it's some conflict with ncurses. Can you apply this patch and build it again from starting from CMake? You'll have to quit this one using Ctrl+C.

[Riiskyy]

You'll have to forgive me, I wasn't sure how to apply the patch but went with a google method and it seemed to work? However I still have the same issue, my outputs are below (i'm using powerline so ignore the formatting).

Oh sorry, I forgot to tell you the commands but you managed everything perfectly.

Let's try this one: https://www.dropbox.com/s/y4vfxqvhl3ls9uq/expand_size.diff?dl=0

Run:

git apply expand_size.diff
make -j8
./tmatrix

and let me know if the rectangles are still there.

[Riiskyy]

hmmm yeah its still the same. I even tried removing the local repo, re-cloning and applying both diffs then rebuilding

[Riiskyy]

Ok so I have tracked it down to a Urxvt problem. If I run it in termite it functions as expected

[M4444]

Ok, can you post the Urxvt issue here so other people can see it if they run into a similar issue? Thanks for trying these fixes.

[Josefan]

I have the same problem with urxvt

[Riiskyy]

I'm not sure exactly what the issue is as I have not found a way to fix it yet. It seems like its some kind of UTF rendering problem in urxvt. I've also tried kitty and that also works jsut fine.

[thor0dinson]

It's missing the katakana font. Install ttf-mplus from AUR. It worked for me.

[Riiskyy]

@thor0dinson strange because I could copy/paste katakana characters in to the terminal and have them display properly, I even tried downloading a katakana font (not the one you listed) and added it as a fallback in my .Xresources but I still had the same issue.

Personally I have now switched over to kitty and have everything working.

[Stock84-dev]

@Riiskyy I managed to get it partially working. Steps: yaourt -S ttf-mplus in ~/.Xresources URxvt.font: yourMainFont,xft:M+ 1c reload config by xrdb ~/.Xresources
and open new terminal There are still a few missing characters.

[M4444]

There are still a few missing characters.

@Stock84-dev It looks like the missing character is 𐌇. You should be able to get it in the ttf-symbola or ttf-code2000 package.

[ndhansen]

Thanks for all your help with this, despite it not being a TMatrix problem. I've installed ttf-symbola and ttf-code2000, but I'm afraid the 𐌇 symbol still isn't rendering in urxvt. Did I make a mistake in my .Xresources file? I've reloaded and everything.

URxvt.font: xft:DejaVu Sans Mono for Powerline:size=10, \
    xft:Kochi Gothic:antialias=false, \
    xft:Baekmuk Gulim, \
    xft:M+ 1m:size=10, \
    xft:Symbola:size=10, \
    xft:Code2000:antialias=false

I've modified the size_temp.cpp file to print the characters, and as you can see everything else works, but it's still missing that one character.
