.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Cstocs is a simple conversion utility to change charset encoding of
a text. It reads either specified files or (if none specified) the
standard input, assumes that the input is encoded in \f(CW\*(C`src_encoding\*(C'\fR
and ties to reencode it into \f(CW\*(C`dst_encoding\*(C'\fR. The result is written to
the standard output.
.PP
Run \f(CW\*(C`cstocs\*(C'\fR without parameters to get short help and list of
available encodings.
.PP
Characters that are not defined in \f(CW\*(C`src_encoding\*(C'\fR are passed to the
output unchanged.
.PP
If source text contains character, that is defined in \f(CW\*(C`src_encoding\*(C'\fR
but not in \f(CW\*(C`dst_encoding\*(C'\fR, it can be handled several ways. For
example, character \*(L"e with caron\*(R" (symbol ecaron), and \*(L"d with caron\*(R"
(symbol dcaron)  are included in the iso\-8859\-2 encoding, but not in
the iso\-8859\-1. If you will do reencoding of 8859\-2 text to 8859\-1,
you may want to do one of the following actions:
.IP "1." 3
Keep it the same, option \f(CW\*(C`\-\-nofillstring\*(C'\fR.
.IP "2." 3
Do not produce any output instead of \*(L"ecaron\*(R" symbol, option \f(CW\*(C`\-\-null\*(C'\fR.
.IP "3." 3
Substitute some string (possibly a space) instead of both ecaron and
dcaron, options \f(CW\*(C`\-\-fillstring\*(C'\fR.
.IP "4." 3
Substitute a letter \*(L"d\*(R" instead of dcaron, and \*(L"e\*(R" instead of ecaron.
It is even possible to substitute string instead of symbol, so you can
replace the \*(L"\s-1AE\s0\*(R" Latin character with string \*(L"\s-1AE\s0\*(R" (letter \*(L"A\*(R", and
letter \*(L"E\*(R").  Or you can replace a \*(L"plusminus sign\*(R" with a string
\&\*(L"+/\-\*(R".  These substitutions are described in the \fIaccent\fR file.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\-i, \-i.ext, \-\-inplace.ext" 4
.IX Item "-i, -i.ext, --inplace.ext"
Files specified will be converted in-place, using Perl \f(CW\*(C`\-i\*(C'\fR facility.
Optionaly, an extension for backup copies may be specified after dot.
This parameter \fBhas\fR to be the first one, if specified.
.IP "\-\-dir directory" 4
.IX Item "--dir directory"
Encoding files are taken from \fIdirectory\fR instead of the default,
which is \fICz/Cstocs/enc\fR in the Perl lib tree. The location of encoding
files can also be changed using the \fI\s-1CSTOCSDIR\s0\fR environment variable,
but the \-\-dir option has the highest priority.
.IP "\-\-fillstring string" 4
.IX Item "--fillstring string"
If source text contains character, that is defined in the
\&\f(CW\*(C`src_encoding\*(C'\fR but not in the \f(CW\*(C`dst_encoding\*(C'\fR nor in the \fIaccent\fR
file (or \fIaccent\fR file is not used), it is replaced by \f(CW\*(C`string\*(C'\fR.
The default is single space.
.IP "\-\-nofillstring" 4
.IX Item "--nofillstring"
Disable changes of characters that would otherwise have fillstring
applied. This is different from \f(CW\*(C`\-\-null\*(C'\fR because that cancels that
character out.
.IP "\-\-null" 4
.IX Item "--null"
Completely equivalent to \-\-fillstring "".
.IP "\-\-nochange or \-\-noaccent" 4
.IX Item "--nochange or --noaccent"
Do not use the \fIaccent\fR file at all.
.IP "\-\-onebyone" 4
.IX Item "--onebyone"
Use only those rules from the \fIaccent\fR file, which rewrite one
character to one character. If this option is specified, character
\&\*(L"ecaron\*(R" will be rewritten to \*(L"e\*(R", but \*(L"\s-1AE\s0\*(R" character will not be
rewritten to \*(L"\s-1AE\s0\*(R" string.
.IP "\-\-onebymore" 4
.IX Item "--onebymore"
Use all rules from accent file. This is the default option.
