I'm in GNU Emacs on OSX. I have copied a line of UTF-8 characters to the Clipboard from Google Chrome. In Emacs eshell-mode, when I do pbpaste, I get garbage characters. How do I correctly paste UTF characters into my Emacs? My coding system is already specified as UTF-8.
pbpaste uses your current locale environment variables for input/output encoding (this is explained in the man page).
I copied a line of accented characters from your referenced file, tried the following with success:
$ LANG=en_US.UTF-8 pbpaste
u00C0: À Á Â Ã Ä Å Æ Ç È É Ê Ë Ì Í Î Ï Ð Ñ Ò Ó Ô Õ Ö × Ø Ù Ú Û Ü Ý Þ
This means that eshell is starting with no LANG environment variable set, and if you provide a value, it works OK.
Add this to your Emacs setup, or type it into eshell:
(setenv "LANG" "en_US.UTF-8")

When I evaluate ruby code blocks inside org-mode I encounter utf-8 errors.
and indeed If i do
#+BEGIN_SRC ruby :exports both :results output
puts RUBY_VERSION
puts __ENCODING__
#+END_SRC
#+RESULTS:
: 2.1.1
: US-ASCII
and when i try to evaluate
#+BEGIN_SRC ruby
'Aurélien'
#+END_SRC
I get this error in Org-Babel Error Output
-:3: invalid multibyte char (US-ASCII)
-:3: invalid multibyte char (US-ASCII)
-:3: syntax error, unexpected end-of-input, expecting keyword_end
'Aurélien'
If I start an inf-ruby buffer I can use utf-8, there is no problem. I think it is a problem with org-babel.
my configuration:
M-x emacs-version 24.4.1
M-x org-version 8.2.10
M-! ruby --version 2.1.1p76
from package list: inf-ruby 20141005.550 installed
In my init file I have
(prefer-coding-system 'utf-8)
(set-default-coding-systems 'utf-8)
(set-keyboard-coding-system 'utf-8)
(set-selection-coding-system 'utf-8)
(set-terminal-coding-system 'utf-8)
(setq buffer-file-coding-system 'utf-8)
(setq erc-server-coding-system '(utf-8 . utf-8))
(setq locale-coding-system 'utf-8)
;; Treat clipboard input as UTF-8 string first; compound text next, etc.
(setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT TEXT STRING))
Is there a setting to change to have utf-8 by default for ruby code blocks and org-babel?
I found the problem.
On my mac, Emacs with a GUI default environment encoding is C.
In my init file, I specified an environment encoding with
(setenv "LANG" "fr_FR.UTF-8")
(setenv "LC_ALL" "fr_FR.UTF-8")
and org-babel picks it up correctly
In windows, I set the variable inferior-lisp-program to be (shell-quote-argument "D:/Program Files/ccl/wx86cl.exe").
But when I run inferior lisp with the command run-lisp, emacs responds:
Searching for program: no such file or directory, "D:/Program
It seemed that emacs treats "D:/Program Files/ccl/wx86cl.exe" as two arguments "D:/Program and Files/ccl/wx86cl.exe" separated by a space character.
How can I make emacs treat "D:/Program Files/ccl/wx86cl.exe" as a whole?
Try using the old "Progra~1" compatibility name for "Program Files". So,
(setq inferior-lisp-program "D:/Progra~1/ccl/wx86cl.exe")
The following specifies file's character encoding:
# -*- coding: utf-8 -*-
But the uppercase variant:
# -*- coding: UTF-8 -*-
produces:
Warning (mule): Invalid coding system `UTF-8' is specified for the
current buffer/file by the :coding tag. It is highly recommended to
fix it before writing to a file.
Version: GNU Emacs 23.3.1
UTF-8 is an official name for the utf-8 character encoding.
The obvious add-to-coding-system-list function doesn't apply in this case. How to make UTF-8 to be alias for utf-8 in the coding declaration?
I think, that following code will help you:
(define-coding-system-alias 'UTF-8 'utf-8)
How can change this behaviour:
C-s — start incremental search
type word — misprint the last character
Backspace — Oops! incremental search disappears, and I actually delete 1 character from the buffer.
to that one:
C-s — start incremental search
word — misprint the last character
Backspace — delete the last d character
type k — work — correct, and continue the search
I run Emacs in text terminal via SSH in PuTTY.
Operating system version: 2.6.16.60-0.58.1.1882.3.PTF.638363-smp #1 SMP Wed Dec 2 12:27:56 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux
Emacs version: GNU Emacs 23.2.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.14.6) of 2010-07-16
With the -q option, Backspace sent by PuTTY is just C-h, and it acts like C-h, but in my .emacsfile I it bind to delete-backward-char:
(global-set-key [(control h)] 'delete-backward-char)
Try this:
(define-key isearch-mode-map [(control h)] 'isearch-delete-char)
What you should do is configure PuTTY to send C-? (byte 127) for Backspace instead of C-h (byte 8). This is the setting that works best in most circumstances. See the
PuTTY manual.
If you changed the PuTTY setting to send C-h because some other application didn't work, check that your terminal settings are correct on the server. The setting is often correctly autodetected, but sometimes you may need to add stty erase '^?' to your shell configuration file (.bashrc or similar) on the server.
If you really absolutely have to have Backspace send C-h, then globally rebinding C-h isn't sufficient. Instead, add (normal-erase-is-backspace-mode 1) to your .emacs. See the Emacs manual.
How you should use Emacs:
C-s - start incremental search
type word - misprint the last character
M-e - goes into edit-search-word-thing-mode-in-minibuffer :-)
correct the typo
C-s - continue incremental search
Here is what I use:

- Mercurial Distributed SCM (version 1.7.2+20101201)
- GNU Emacs 24.0.50 (build from git repo with --cocoa flag)
- aHg v0.99
Here is my emacs settings:

Running hg log under M-x term gives me a correct result I can read (? is a russian chars...). So... How can I fix this in Emacs in aHg output?
First thing, that should be checked here - which LANG is set when Emacs was started)? (what is returned when you execute M-: (getenv "LANG")? As I remember, Mac OS X set LANG to "C" on the start of launchpad... setting of language environment don't modify LANG...
You can explicitly set the LANG environment from Emacs using (setenv "LANG" "ru_RU.UTF-8") or use "en_EN.UTF-8" if it preferable.
P.S. I just checked ahg with different LANG settings, and see question marks when I set LANG to "C", and see Russian letters when I run ahg-log in repository
It could be that the default font that is being used for output when you do C-c h g s doesn't support Cyrillic characters. You can see what font is being used by placing the point on one of the Russian characters that isn't being displayed properly and pressing C-u C-x =. To ensure that Russian is always displayed properly in Emacs, you can specify that all Russian characters will be displayed in a particular font. Since the Cyrillic characters are in the Unicode range U+0400 – U+04FF and the Arial font seems to display these characters ok, you could try the following in your Emacs init file:
(set-fontset-font "fontset-default"
'(#x400 . #x4ff)
"Arial")
