The iconv command is used to convert the encoding of a file from one character set to another. A character set is a collection of characters that are assigned numerical values called code points. Different character sets may use different numbers of bytes to represent each character, and may have different mappings of code points to characters. For example, ASCII is a single-byte character set that encodes 128 characters, while UTF-8 is a variable-length character set that can encode over a million characters. The iconv command can convert between many different character sets, such as ASCII, UTF-8, ISO-8859-1, etc. The basic syntax for using the command is as follows:
iconv [options] -f from-encoding -t to-encoding input-file > output-file The -f option specifies the encoding of the input file, and the -t option specifies the encoding of the output file. The input file is read from standard input, and the output file is written to standard output, unless specified otherwise. The iconv command can also list all the supported character sets with the -l option1234. Reference:
