Hi. I'm using emacs as a text editor (I'm not a programmer), and need some
advice:
I'm running emacs 21.3 in Windows, and need to read and edit some text files
with UTF-8 encoding and others with escaped unicode encoding. I've managed
to get emacs to display the UTF-8 files correctly, but not the escaped
unicode ones. The alphabet is Latin, but accented characters are not being
displayed properly in the escaped unicode files. What do I need to do to
get emacs to display the characters properly, regardless of whether I go
into a UTF-8 or an escaped unicode file?
I have to say, I don't really understand what what the coding means -- all I
know is that I have these files to work with and want to use emacs to edit
them. I'd appreciate any help.
Thank you

What is an "escaped unicode" file? Can you attach a small sample file
to your reply?

If escaped unicode is a sequence of hexadecimal tetrads like \x00c0 or
\u00ce then David Love's ucs-tables.el could be used to convert them to
the glyphs at the corresponding Unicode code points by reading each "word"
or token in the file and then passing it to ucs-insert. You would then see
the foreign language character as long as you had an appropriate font or
font-set installed. I've heard that we have to wait for Emacs 23 before we
see seamless Unicode support. Even version 22 (CVS) handles these
characters better than the version I use (21.3). It's common to see
escaped octal representations with version 22.0 probably because the unify
on encoding and decoding aren't folding together the "same" characters
produced using different input methods.

According to the folks at Mozilla, Escaped Unicode Encoding uses the unicode
representation \uXXXX.
I've attached a small file with characters encoded in this way. It includes
three "special" characters:
a "u" with a circumflex, an "a" with a circumflex, and a "c" with a cedilla.
I can't get emacs to read them properly: they appear, respectively, as:
"\u00FB", "\u00E2", "\u00E7"
If you can get emacs to read the file properly, please let me know how you
did it.
Thanks

Thank you for your reply. I've looked at a description of "ucs-tables.el",
and I think I need things described in layman's terms.
Is this a plugin of some sort for emacs that will convert the characters
into something readable? If so, what happens when I use emacs to edit the
file? Will the characters retain their unicode-ness to satisfy the
applications that require the \uXXXX format? And how will any new accented
characters be encoded?
Thank you.

M-x ucs-insert is for manual insertion of arbitrary (or at least the ones
included in alists in ucs-tables.el) unicode characters. This function is
defined toward the end of ucs-tables.el. If just the sets of four hex
digits are entered in the mini-buffer (one set at a time), the characters
ûâç
are inserted at point.
This is not a plug-in but just an interactive function that can be invoked
with Meta-x. It's designed for manual, one at a time, insertion of
characters, not for rendering a whole file.

It's getting better. You can type for example C-s ä RET and search
for an ``ä´´ in few encodings – but still not in all! (I should
submit another bug report on this ...)

If you have the previously mentioned `ucs-insert' function (either by
running Emacs 22, or from Dave Love's code for earlier emacs), you can
use a simple function like the following to do the whole buffer:
(defun expand-ucs-escapes ()
(interactive)
(save-excursion
(goto-char (point-min))
(while (re-search-forward "[\\]u\\([0-9a-f][0-9a-f][0-9a-f][0-9a-f]\\)"
nil t)
(let ((code (match-string 1)))
(delete-region (match-beginning 0) (match-end 0))
(ucs-insert code)))))
[Invoke it as "M-x expand-ucs-escapes" or bind it to a key or something.]
