Unicode Strings in Emacs Info C-h i

Unicode Strings in Emacs Info C-h i

[Mike Vertolli]

I'm stumped at this point. Initially the values were displayed with escapes
(e.g., /u2018). I swapped the localization to en_US.UTF-8 and now they are
being displayed as small, square, filled-in boxes. Re-coding in the editor
has no effect (already reading the file as UTF8).

I'm running a Gentoo distro. I'd rather not have to find and replace.

Thanks in advance,

This might be a good sign, really :-)

My hunch is that Emacs displays the correct (Unicode) characters, but that
you don't have a suitable font (set).

As a first approach, put point on one of those little boxes and enter

  M-x describe-char

What happens?

You might want to install a more complete font. Unless you *want* to have
(non-ascii) Unicode characters displayed as \u2018, that is. In that case...
there should be an option for that, but I'd have to look it up, sorry.

Something i've found really useful to help maximise the number of 
Unicode glyphs available for display is the `unicode-fonts` 
package:

https://github.com/rolandwalker/unicode-fonts

which is available from MELPA:

http://melpa.org/#/unicode-fonts

It is not enough to set the locale to UTF-8, you need also to make
sure that your console or terminal emulator support a large enough
range of Unicode codepoints.  The way you did it, Emacs sees your
locale and assumes your terminal can display these characters, so it
sends their UTF-8 codes to the terminal.  But the terminal doesn't
know how to display them.

To expand on Eli's reply....  Try running Emacs in X instead of in the
terminal emulator.  If the UTF characters are displayed correctly then
the problem is your terminal emulator.
