[SOLVED] Emojis on rxvt-unicode

Message

I am having a bit of a problem getting Unicode emojis to render on rxvt-unicode. So far, I've installed the font "Emojione Color".
I've also added this entry to ~/.Xresources and merged it with xrdb:

Code: Select all

URxvt*font: xft:DejaVu Sans Mono:size=10,xft:Emojione Color:size=10
URxvt*letterSpace: -2

I've also checked the spelling to make sure I didn't say "colour" instead of "color". And yet, emojis refuse to render properly -- only appearing as square boxes.

What should I do?

EDIT:

.ps 36
.ft B
SOLVED: SOLUTION:
.ft R
Use xterm or st.

urxvt only supports the first 64K characters. Install a terminal that doesn't lie about its unicode support, like st or xterm.

Interesting... I like urxvt, but this might be a reason to change. So... urxvt supports "utf-6"?

st sure is "pure" in it's design. It should replace xterm as a "default" term in xorg (imo).

urxvt only supports UCS-2, like Windows 2000 or Java 1.3. The author is one of those types that gets angry if you so much as point out bugs, so it'll likely never be fixed (same goes for its use of manually-premultiplied alpha transparency and color escape code parsing).

st's unicode isn't perfect, it doesn't know some characters should be double-width, but at least it's trying.

I wonder how's the support on other terminal emulators then... Like Konsole, xfce-terminal or even alacritty.

AFAIK most of the heavyweight terms nowadays are just wrappers around libvte, which should get this stuff right.

Thanks for the info on terminals, Ant P. You seem to know quite a bit about terminal emulators; are there any that can mimic urxvt's Ctrl+Shift (ISO 14755 mode) behavior? For example, I can hold Ctrl+Shift, then press 2665. When I let go of the modifier keys, it prints ♥, as expected. I know GTK+ enabled terminal emulators have Ctrl+Shift+u <numbers><Enter>, but urxvt's chord feels more natural. Do other terminal emulators offer anything like that?

urxvt's is done via a perl plugin iirc. No idea if others have anything like that.

XCompose is a better way of doing unicode imo: it works in any window (even Wine ones), and the default list (in /usr/share/X11/locale/en_US.UTF-8/Compose) covers nearly everything I can think of wanting to use regularly. Note that it makes heavy use of "<Multi_key>" which defaults to shift+altgr (not altgr+shift!)
