unaccent(1)						      General Commands Manual						       unaccent(1)

NAME

       unaccent - remove accents from input stream or a string

SYNOPSIS

       unaccent [--debug_low] [--debug_high] [-h] charset [string] [expected]

DESCRIPTION

       With  a	single argument, unaccent reads data from stdin, replaces accented letters by their unaccented equivalent and writes the result on
       stdout.	If the second argument ('string') is provided unaccent transforms it by replacing accented letters by their unaccented equivalent.
       The  result  is	printed on the standard output.  The charset of the input string or the data read from stdin is specified by the 'charset'
       argument (ISO-8859-15 for instance). The output is printed using the same charset.

       If the 'expected' argument is provided, the output string is compared to it. If they are not equal unaccent exits on error.

       unaccent relies on the iconv(3) library to convert from the specified charset to UTF-16BE (or UTF-16 if UTF-16BE  is  not  available).  You
       should check the manual pages for available charsets. On GNU/Linux the command

       iconv -l

       shows all available charsets.

OPTIONS

       --debug_low
	      Prints human readable information about the unaccentuation process. See unac(3) for more information.

       --debug_high
	      Prints very detailed information about the unaccentuation process.  See unac(3) for more information.

       --help -h
	      Prints a short usage and exits.

EXAMPLES

       Remove accents from the string ete and check that the result is ete.

       unaccent ISO-8859-1 ete ete

       Remove accents from file myfile and put the result in file myfile.unaccent

       unaccent ISO-8859-1 < myfile > myfile.unaccent
