how to enable italic font in terminal emacs?

how to enable italic font in terminal emacs?

[Shiyao MA]

Hi,

I am using iterm2 + tmux.

The term supports italic font,  for example:
printf "\e[3;4;33mthis is a test\n\e[0m"

it prints out italic text in the shell running in iterm2+ tmux.


However, in terminal emacs, I cannot get italic font.

For example, in orgmode with the text:
/my-italic-text/
it simply doesn't become italic.


Best,

This seems relevant:

  <https://unix.stackexchange.com/questions/17680/italics-in-emacs-on-a-text-terminal-rxvt-unicode>

In short: for a sufficiently recent Emacs, it Just Works :)
(I tested it on "my" Emacs, which is GNU Emacs 26.0.50 (build 1,
x86_64-pc-linux-gnu, GTK+ Version 2.24.29) of 2017-07-25; I do
build from sources), and it actually works, on a plain Xterm.

I don't know at which version the patch got in, sorry.

Cheers

Emacs supports italics on text terminals since round about
version 24.1 in beginning of 2012.

Now it also does so with screen (1) (atm unreleased) master since
2017-07-09.

HTH, gregor
