Ubuntu Manpage: uniconv - convert text to native formats through Unicode

NAME

       uniconv - convert text to native formats through Unicode

SYNOPSIS

       uniconv -out output-file [ -decode input-encoding ] [ -encode output-encoding ] [ input-file ] [ -todos ]
       [ -fromdos ] [ -tomac ] [ -frommac ]

DESCRIPTION

       uniconv program decodes scripts with a certain encoding encodes them with some other encoding.  The scipt
       is a 16,8 or 7 bit-byte stream.  The converted text  will be sent to the standard output, even in case of
       16-bit encoding methods,unless the output file is specified by the -out option.

       The  -decode  and  -encode  options  are optional, the default converter is utf-8.  The program reads the
       Unicode map helper files (*.my) from the  default  directory  /usr/share/data.   Simple  1-to-1  encoding
       methods  can  be  added  on  the  fly  by  adding a a my-file, or setting your yudit.datapath property in
       ~/.yudit/yudit.properties or /usr/share/yudit/config/yudit.properties.  By default  /usr/share/yudit/data
       and ~/.yudit/data are searched.

       My-files  can  be created by a program called The files can be converted between dos/unix/mac line-ending
       variants with -fromdos, -frommac, -todos, -tomac options. the  default  (not  scpecified  one)  is  Unix.
       makeumap.

ENCODING

If you received this program through the Yudit distribution, then as of today you can convert between the
encoding methods below.

utf-8 Yudit recommends this format for international information exchange. ASCII text will get
through intact, while other Unicode characters will get their 8th bit set and the length of the
code will depend on how far away they are in the Unicode space. This is the only transformation
format that can encode both 16-bit (ucs-2) and 31-bit (ucs-4) Unicode.

utf-8-s
Hackers utf-8 format - it does not give an error message when a surrogate pair is decoded and it
can encode a surrogate pair 'as is'. This is not a recommended encoding format although this
format is used to encode/decode clipboard data, in order to preserve input.

utf-16 Although 16 is bigger than 8 this is still a compromise required by OSes like Windows that can not
handle ucs-4 - this encoding produces 16-bit Unicode streams. In addition to BMP it can convert
16 planes using the Unicode Surrogate Area. This encoding can not convert anything above U+10FFFF
(Plane 16). The input byte order is recognized by the first two characters BEM (byte-order-mark)
U+FEFF. This format is used in Windows NT for documents like notepad .txt files.

utf-16-be
Big endian utf-16 converter.

utf-16-le
Littlen endian utf-16 converter.

utf-7 This is the recommended format for international information exchange, when 7-bit can only be
used. It can only handle 16-bit (utf-16) Unicode, for ucs-4 (above U+10FFFF) you should use utf-8
encoding.

X 0213 standard.

euc-jp This is a Japanese character encoding format. It is an 8-bit encoding format. Mainly used in UNIX
systems.

euc-jp-3
The official name is EUC-JISX0213 - I just could not read this. This is a Japanese character
encoding format. It is a 8-bit encoding format. It is base upon JIS X 0213 standard.

This is a Japanese 7-bit character encoding format. The iso-2022-jp email messages can be
decoded/encoded are in this format.

iso-2022-x11
This is a Japanese character encoding format. It is also known as "COMPOUND_TEXT" encoding for
the X Window System. This is a 7-bit encoding format. It can be derived from the ISO 2022-JP
format with some differences.

ksc-5601-x11
This is a Korean character encoding format used by the X window system(COMPOUND_TEXT encoding)
to encode Korean(KS X 1001) and US-ASCII. This is a 7bit encoding format compliant to ISO-2022
specification for encoding of multiple character sets. Please, note that this is DIFFERENT from
ISO-2022-KR (defined in IETF RFC 1557).

euc-kr This is an 8bit multibyte encoding for Korean. It encodes US-ASCII(7bit) in single byte range
and characters in KS X 1001(formerly KS C 5601) in double byte range with MSB on(8bit). It's used
in Unix and Internet. Korean version of MS-DOS, MacOS and MS-Windows use compatible (most cases,
identical) variant of this encoding.

johab This is a Korean encoding specified in KS X 1001(KS C 5601-1992), Annex 3 as a
supplementary encoding. Widely used in Korean MS-DOS until mid-1990's. It can encode all
Hangul syllables(11,172) of modern Korean as well as all the special symbols and Hanja (Chinese
ideograms used in Korea) defined in KS X 1001.

uhc A variant of EUC-KR used in Korean MS-Windows 95/98(proprietary encoding of
Microsoft,CP949). Its character repertoire includes all modern syllables of Hangul,Korean
script as well as all the special symbols and Hanja (Chinese ideograms used in Korea) defined in
KS X 1001.

gb-18030
This is a Chinese character encoding format based upon GB 18030. It encodes the whole
U+0000..U+10FFFF range, while being compatible with gb-2312.

gb-2312-x11
This is a Chinese character encoding format based upon GB 2312. It is a 7-bit encoding format.

gb-2312
This is a Chinese character encoding format based upon GB 2312. It is an 8-bit encoding format.

big-5 This is a Chinese character encoding format based upon BIG5 encoding. It is an 8-bit encoding
format.

hz This is a Chinese character encoding format based upon "Hanzi" encoding. It is a 7-bit encoding
format.

viscii This is a Vietnamese character encoding format.

ucs-2-be
This converts 16-bit Unicode (ucs-2) streams. The format takes care of big-endian variant. Yudit
does not recommend this format.

ucs-2-le
This converts 16-bit Unicode (ucs-2) streams. The format takes care of little-endian variant.
Yudit does not recommend this format.

ucs-2 This converts 16-bit Unicode (ucs-2) streams. The input byte order is recognized by the first two
characters BEM (byte-order-mark) U+FEFF. Yudit does not recommend this format.

java This converts \uxxxx character escapes. When encoding, all characters above U+0080 will be escaped
with a string like '\u0080'. When decoding the same format is decoded but, in addition, utf-8
format is also recognized, so it can also be used to recover data accidentally saved with the
wrong encoding. The U+10000..U+10FFFF area is converted to surrogates and vice versa.

java-s This converts \uxxxx character escapes. When encoding, all characters above U+0080 will be escaped
with a string like '\u0080'. When decoding the same format is decoded but, in addition, utf-8
format is also recognized, so it can also be used to recover data accidentally saved with the
wrong encoding. Surrogates are not treated specially during conversion - this is why it is not a
recommended conversion.

FILES

       ~/.yudit/yudit.properties or /usr/share/yudit/config/yudit.properties
              can  have  yudit.datapath  property.  This  is  where  the  map  files  are  kept.    By   default
              /usr/share/yudit/data is searched.
