iconv - Windows command-line utility to convert encoded characters to another code set
iconv -f fromCode -t toCode [-s char] [file...]
The iconv Windows command-line utility converts the encoding of characters in file from one coded character set to another, and writes the results to standard output.
The input and output coded character sets are identified by fromCode and toCode. If the file argument is not specified on the command line, the iconv command reads the standard input.

If no conversion exists for a particular character, it is converted to the substitute character in the target code set.
The iconv utility accepts the following options and arguments:
