The main program to convert from any code to any other code is iconv, please
type:
$ iconv —list
in order to realize the number of codes that our world produces before UNICODE.
$ iconv -f ISO-8859-1 -t UTF-8 essai-iso8859-1.tex > essai-utf-8.tex
will transform from former ISO-8859-1 to Unicode (utf-8).
$ iconv -f CP850 -t UTF-8 essai2-CP850.tex > essai2-utf-8.tex
will transform from Windows CP850 to Unicode.
After the move from 7bit character or ASCII, to 8 bit (allowing 128 new
characters) there was not enough space, even for all Western roman characters
and iso8859-1, iso8859-2 etc. did appear in the early 80’s. At that time,
scientific publishers were publishing in non English reviews and the TeX
meeting in Cork was the premises for adopting multiple characters for a single
sign: unicode.
Unicode has been adopted by Linux, Windows and Apple since about 2001! All the
internal text files of the Operating System are coded in Unicode. But the
habits of users let former codes survive. And some people are still using cp850
or iso-8859-1 for their text files.
But your question concerns probably the transformation of the family of TeX
backslash accented characters, \’e or {\’e} to é. Such software (tex7a8 for 7
bit/ASCII to 8bit) was distributed by the French TeX association GUtenberg in
the early 90’s on diskettes!
I am using my own emacs lisp macro and still use it for old tex files. Here is
some excerpts from my 1992 macro file named tex7a8.el (the octal character \300
for acute A has to be entered)
(defun tex-pc850-ascii ()
"Fonction pour convertir un fichier TeX 8 bits PC850 en codes 7 bits ASCII."
(interactive)
(setq case-fold-search nil)
(beginning-of-buffer)
(while (not (eobp)) (end-of-line) ;
(delete-horizontal-space) (if (not (eobp)) (next-line 1)))
(beginning-of-buffer) (replace-string "% TEX 8(pc850)" "% TEX 7(ascii)” )
(beginning-of-buffer) (replace-string “\300" "\\`A” )
.. ..
);(global-set-key "\C-z7" 'tex-88591-ascii)
Under emacs, you can easily transform a buffer 'essai-8859-1.tex' encoded
iso-8859-1 in Unicode by typing prefixing the ctrl_x ctrl_w (for writing a
buffer to a file) by ctrl_x return c. You are then invited to choose your
output encoding. utf-8-unix, for example, differs from utf-8-dos by the fact
that each line which under unix ends with a LF (linefeed) will end with two
characters, Carriage Return (^M) and Line Feed (^J) as required by Windows.
Usually the command unixtodos does the conversion. Thus for me, to transform a
LaTeX text from Ascii to Unicode under Emacs, I first transform it in whatever
8bit and then use emacs-iconv.
I know that publishers are reluctant to offer both pdflatex and xelatex. But
most of time, you can submit your text encoded in Unicode, for European
languages only.
