How do I deal with Unicode in Emacs?
Dealing with unicode in Emacs is a daily task for me. Unfortunately, I don’t have the luxury of sticking to just UTF-8 or iso-8859-1; my work involves a lot of fidgeting with a lot of coding systems local to particular regions, so I need a flexible editor that has the right defaults that will cover my most common use-cases.
What’s the new command line argument in Emacs?
The new command-line argument ‘–dump-file=FILE’ allows specifying a non-default “.pdmp” file to load the state from; see the node ” (emacs) Initial Options” in the Emacs manual for more information. An Emacs started via a dump file can create a new dump file only if it was invoked with the ‘-batch’ option.
Can you force Emacs to default to UTF-8?
Emacs has facilities in place for changing the coding system for a variety of things, such as processes, buffers and files. You can also force Emacs to invoke a command with a certain coding system, a concept I will get to in a moment. The most important change (for me, anyway) is to force Emacs to default to UTF-8.
Which is the older version of Emacs perfecly?
This is a game changer to people who use language server tools like eglot or lsp-mode, or any other tool that (de)serializes a lot of JSON. The older implementation is perfecly fine, but it’s slow, as it’s written in elisp.
Which is the default coding system in Emacs?
The biggest issue is convincing Emacs to treat files as UTF-8 by default, when no information in the file explicitly says it is. I use the following code snippet to enforce UTF-8 as the default coding system for all files, comint processes and buffers. You’re free to replace utf-8 below with your own preferred coding system.
What does UCS-insert do in Emacs version 24?
Command ‘ucsc-insert’, a replacement for ‘insert-char’(‘ucs-insert’for Emacs before version 24) — bind it to ‘C-x 8 RET’. It does the same thing, except that with a negative prefix argument(for which ‘ucs-insert’does nothing) it automatically creates such a command.
