utf8trans(1)
NAME
utf8trans - Transliterate UTF-8 characters according to a table
SYNOPSIS
utf8trans charmap [file]...
DESCRIPTION
utf8trans transliterates characters in the specified files (or standard input, if they are not specified) and writes the output to standard output. All input and output is in the UTF-8 encoding. This program is usually used to render characters in Unicode text files as some markup escapes or ASCII transliterations. (It is not intended for general charset conversions.) It provides functionality similar to the character maps in XSLT 2.0 (XML Stylesheet Language -- Transformations, version 2.0).
OPTIONS
-m, --modify
Modifies the given files in-place with their transliterated
output, instead of sending it to standard output.
This option is useful for efficient transliteration of many
files at once.
--help Show brief usage information and exit.
--version
Show version and exit.
USAGE
The translation is done according to the rules in the 'character map',
named in the file charmap. It has the following format:
1. Each line represents a translation entry, except for blank lines
and comment lines, which are ignored.
2. Any amount of whitespace (space or tab) may precede the start of an
entry.
3. Comment lines begin with #. Everything on the same line is
ignored.
4. Each entry consists of the Unicode codepoint of the character to
translate, in hexadecimal, followed one space or tab, followed by
the translation string, up to the end of the line.
5. The translation string is taken literally, including any leading
and trailing spaces (except the delimeter between the codepoint and
the translation string), and all types of characters. The newline
at the end is not included.
The above format is intended to be restrictive, to keep utf8trans
simple. But if a XML-based format is desired, there is a
xmlcharmap2utf8trans script that comes with the docbook2X distribution,
that converts character maps in XSLT 2.0 format to the utf8trans
format.
LIMITATIONS
* utf8trans does not work with binary files, because malformed UTF-8
sequences in the input are substituted with U+FFFD characters.
However, null characters in the input are handled correctly. This
limitation may be removed in the future.
* There is no way to include a newline or null in the substitution
string.
