[-p|--perlqq|--htmlcref|--xmlcref] [-C N|-c] [-D] [-S scheme]
[-s string|file...]
piconv -l
piconv -r encoding_alias
piconv -h
Common options:
-l,--list
lists all available encodings
-r,--resolve encoding_alias
resolve encoding to its (Encode) canonical name
-f,--from from_encoding
when omitted, the current locale will be used
-t,--to to_encoding
when omitted, the current locale will be used
-s,--string string
"string" will be the input instead of STDIN or files
The following are mainly of interest to Encode hackers:
-C N | -c check the validity of the input
-D,--debug show debug information
-S,--scheme scheme use the scheme for conversion
Those are handy when you can only see ASCII characters:
-p,--perlqq transliterate characters missing in encoding to \x{HHHH}
where HHHH is the hexadecimal Unicode code point
--htmlcref transliterate characters missing in encoding to &#NNN;
where NNN is the decimal Unicode code point
--xmlcref transliterate characters missing in encoding to &#xHHHH;
where HHHH is the hexadecimal Unicode code point
