konwert - interface for various character encoding conversions SYNOPSIS
Konwert allows filtering multiple files through multiple filters. It filters the specified FILEs, or stdin if none are given. Simple FILTER is the name of an executable file from the directory ~/.konwert/filters or the system-wide one, normally /usr/share/kon- wert/filters. Such program itself filters stdin to stdout. The filtering rule can be more complex: konwert FILTER1+FILTER2 means konwert FILTER1 | konwert FILTER2. konwert FORMAT1-FORMAT2, unless such filter exists, tries to find a common FORMAT3, such that both filters FORMAT1-FORMAT3 and FORMAT3-FOR- MAT1 do exist. konwert FILTER/ARG/... passes arguments to the filter. Arguments can also be specified here: FORMAT1/ARGS-FORMAT2. The meaning of argu- ments depends on the particular filter. konwert '(COMMAND ARGS...)' executes this arbitrary shell command. This is useful with -o or -O options. The command cannot contain the string )+, which will terminate this filter's specification. OPTIONS -o DEST output goes to this file/directory instead of stdout -O every input file is replaced with its translation --help display help and exit --version output version information and exit Redirecting output to one of the source files with either -o or > instead of -O will corrupt it! Option -O creates a temporary file in /tmp and later copies it back onto the source. CHARACTER ENCODING CONVERSIONS
You can convert text between any two charsets, for example konwert cp437-iso2. Characters unavailable in the target charset will be substituted with approximations with available ones. The approximations need not be single characters. The following character sets are currently supported: ascii 7bit ASCII utf8 = unicode Unicode UTF-8 iso1 = isolatin1 ISO-8859-1 aka ISO Latin 1 (Western European) iso2 = isolatin2 ISO-8859-2 aka ISO Latin 2 (Central European) iso3 = isolatin3 ISO-8859-3 aka ISO Latin 3 (Esperanto) iso4 = isolatin4 ISO-8859-4 aka ISO Latin 4 (Baltic) iso5 = isolatincyr ISO-8859-5 (Cyrillic) iso6 = isolatinarabic ISO-8859-6 (Arabic) iso7 = isolatingreek ISO-8859-7 (Greek) iso8 = isolatinhebrew ISO-8859-8 (Hebrew) iso9 = isolatin5 = isolatintur ISO-8859-9 aka ISO Latin 5 (Turkish) iso10 = isolatin6 = isolatinnordic ISO-8859-10 aka ISO Latin 6 (Nordic) iso12 = isolatin7 = isolatinceltic ISO-8859-12 aka ISO Latin 6 (Celtic) - Draft iso13 = isolatin8 = isolatinbaltic ISO-8859-13 aka ISO Latin 6 (Baltic) - Draft iso14 = isolatin9 = isolatinsami ISO-8859-14 aka ISO Latin 6 (Sami) - Draft iso15 ISO-8859-15 - Draft koi8r KOI8-R (Russian) koi8u KOI8-U (Ukrainian, Byelorussian) koi8uni KOI8-Uni (Cyrillic) cp1250 = wince = winlatin2 Windows CP-1250 aka Win Latin 2 (Central European) cp1251 = wincyr Windows CP-1251 (Cyrillic) cp1252 = winwest = winlatin1 Windows CP-1252 aka Win Latin 1 (Western European) cp1253 = wingr Windows CP-1253 (Greek) cp1254 = wintur Windows CP-1254 (Turkish) cp1255 = winhebrew Windows CP-1255 (Hebrew) cp1256 = winarabic Windows CP-1256 (Arabic) cp1257 = winbaltic Windows CP-1257 (Baltic) cp1258 = winviet Windows CP-1258 (Vietnamese) cp437 = icmeng DOS CP-437 (English) cp737 = dosgreek DOS CP-737 (Greek) cp775 = dosbaltic DOS CP-775 (Baltic) cp850 = doswest = doslatin1 DOS CP-850 aka DOS Latin 1 (Western European) cp852 = dosce = doslatin2 DOS CP-852 aka DOS Latin 2 (Central European) cp855 = doscyr DOS CP-855 (Cyrillic) cp857 = dostur DOS CP-857 (Turkish) cp860 = dosportugal DOS CP-860 (Portugal) cp861 = dosiceland DOS CP-861 (Icelandic) cp862 = doshebrew DOS CP-862 (Hebrew) cp863 = doscanadfr DOS CP-863 (Canadian French) cp864 = dosarabic DOS CP-864 (Arabic) cp865 = dosnordic DOS CP-865 (Nordic) cp866 = dosrussian DOS CP-866 (Russian) cp869 = dosgreek2 DOS CP-869 (Greek2) cp874 = dosthai DOS CP-874 (Thai) mac Macintosh Roman (Western European) macce Macintosh Central European maccyr Macintosh Cyrillic macgreek Macintosh Greek maciceland Macintosh Icelandic mactur Macintosh Turkish csk, cyfromat, dhn, fidomazovia, iea, logic, mazovia, microvex DOS charsets for Polish amigapl, fat, xjp Amiga charsets for Polish kamenicky DOS charset for Czech and Slovak wingreek WinGreek (Windows font-based encoding for ancient Greek) babelpl TeX [polish]{babel}: "a"c"e"l"n"o"s"z"r ciachy TeX prefixing: /a/c/e/l/n/o/s/x/z xmetodo Esperanto: cx gx hx jx sx ux (vx w) hmetodo Esperanto: ch gh hh jh sh u antauxcxap Esperanto: ^c ^g ^h ^j ^s ^u (~u) postcxap Esperanto: c^ g^ h^ j^ s^ u^ (u~) apostrofoj Esperanto: c' g' h' j' s' u' malapostrofoj Esperanto: c` g` h` j` s` u` viscii VISCII (Vietnamese) viqri Vietnamese Quoted Readable Implicit htmldec SGML/HTML character references (decimal): Æ ě → htmlhex SGML/HTML character references (hexadecimal): Æ ě → htmlent SGML/HTML character entities (names): Æ &ecaron → html All three above (only as input format) tex TeX with some LaTeX or AMS-TeX extensions. There is no distinction between normal and math mode - you will probably have to insert some $'s manually. mnemonic RFC 1345 mnemonics preceded by & mnemonic1 RFC 1345 mnemonics preceded by ` any/LANGUAGE (e.g. any/pl-iso2) This special input format will detect the encoding automatically, basing on the frequencies of characters found in text. Every lan- guage is associated with a set of possible encodings used for it and average frequencies of its letters (excluding ASCII letters). The best fitting encoding is used for conversion. Currently supported languages are cs (Czech), de (German), el (Greek), eo (Esperanto), es (Spanish), fr (French), he (Hebrew), it (Italian), pl (Polish), pt (Portuguese), ru (Russian), and sv (Swedish). varpl Mixed Polish ISO-8859-2, CP-1250, and UTF-8. If you are reading Polish newsgroups I suggest putting it as a filter in your news- reader (for speed improvement it's better to call it directly, rather than through konwert). vareo Mixed various Esperanto encodings. OPTIONS CONTROLLING THE ABOVE CONVERSIONS
/1 (e.g. konwert iso2-ascii/1) Each unavailable character will be replaced only with a single approximate char, not string. This is useful with the filterm program or with preformatted text. This option is automatically turned on when a filter is used as output for filterm. /html Text is assumed to be HTML. The characters " & < > resulting from other characters' approximations will be properly escaped as &quot; &amp; &lt; &gt;. The <META http-equiv="content-type" content="text/html; charset=..."> header will be fixed if present. /htmldec Convert META as above. Unavailable characters will be encoded in &#Unicode;. /htmlhex Convert META as above. Unavailable characters will be encoded in hexadecimal &#xUnicode;. /tex Unavailable characters will be described in TeX. Characters # $ % & ^ _ { | } ~ resulting from some characters' approximations will be properly escaped into # $ \% & $ackslash$ ^{} \_ { $|$ } ~{}. /asciichar Recognizes some ASCII representations of characters, e.g. (c) ... 1/2 >=. /rosyjski Russian text will be replaced with its Polish phonetic transcription. Some output filters can use the language information for choosing better approximations of unavailable letters, for example /de (German): a -> ae instead of a. OTHER FILTERS
any/LANGUAGE-test Detects the encoding, but instead of text conversion only shows the encoding's name. The additional option /all shows all possible encodings, sorted from better to worse ones. cr lf crlf Force specific end-of-line marker convention. cr = Macintosh, lf = Unix and Amiga, crlf = Windows and DOS. The input convention is detected automatically. expand Expands tabs into spaces (uses the textutils program expand). unexpand Compresses spaces into tabs (uses the textutils program unexpand). rmspacesateol Removes spaces and tabs at end of line. qp-8bit 8bit-qp MIME Quoted Printable encoding: =A3=F3d=BC. rtf-8bit 8bit-rtf Rich Text Format: 'a3'f3d'9f. txt-htmlchar Escapes " & < > into SGML/HTML entities &quot; &amp; &lt; &gt;. Useful for including a text file inside HTML <PRE> </PRE> tags. htmlchar-txt Reverse. rot13 Guvf vf n qrzbafgengvba bs ebg13. toupper tolower Self-explanatory. Currently ASCII only. prn7pl Converts polish chars to control sequences for EPSON-compatible printer. Using only 7-bit chars, backspacing printer's head and ver- tical positioning chars ,.'` it creates pseudo-polish gryphs. You can specify options: /nlq (default) which optimalizes output for better quality printers and /draft - useful for ex. for 9-nails printer. FILES

trs(1), filterm(1) BUGS
APPLE character in mac* charsets, and CH and ch characters in koi8cs are not preserved in conversion even when they are available. Also they don't respect the /1 option. Reason: they are not in Unicode. COPYRIGHT
