gauche-cesconv - Man Page

convert text from one character encoding scheme to another


gauche-cesconv [-h] [-f encoding] [-t encoding] [-o outfile] [infile]


The gauche-cesconv command is a program to convert text from one character encoding scheme (CES) to another, using Gauche's character conversion module. Hence the supported character sets are the same as Gauche's. See the info document of Gauche for more details.

There are other commands that provide the same functionality and more, such as iconv(1) or nkf(1), but they are not universally available by default. This command is provided for Gauche's external packages to ease the installation and configuration process; for those packages, it is certain that gauche-cesconv is available, so they don't need to check availability of iconv etc.

When infile is omitted, the text is read from standard input.


-f,  --from-code=encoding

Selects input encoding. Can be ´*JP´ to guess the character encoding from japanese text, among either ISO2022-JP(-1,2,3), EUCJP, SHIFT_JIS or UTF-8. If omitted, gauche´s native CES is used.

-h,  --help

Show summary of options.

-o,  --output=outfile

Place output in file outfile. If omitted the converted text is written to standard output.

-t,  --to-code=encoding

Selects output encoding. (see also --from-code)


gauche-cesconv exits with status 0 on success.
