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 "src_encoding" and ties to reencode it into "dst_encoding". The result is written to the standard output.
Run "cstocs" without parameters to get short help and list of available encodings.
Characters that are not defined in "src_encoding" are passed to the output unchanged.
If source text contains character, that is defined in "src_encoding" but not in "dst_encoding", it can be handled several ways. For example, character "e with caron" (symbol ecaron), and "d with caron" (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:
1. |
Keep it the same, option "−−nofillstring". |
||
2. |
Do not produce any output instead of "ecaron" symbol, option "−−null". |
||
3. |
Substitute some string (possibly a space) instead of both ecaron and dcaron, options "−−fillstring". |
||
4. |
Substitute a letter "d" instead of dcaron, and "e" instead of ecaron. It is even possible to substitute string instead of symbol, so you can replace the " AE " Latin character with string " AE " (letter "A", and letter "E"). Or you can replace a "plusminus sign" with a string "+/−". These substitutions are described in the accent file. |
−i, −i.ext, −−inplace.ext
Files specified will be converted in-place, using Perl "−i" facility. Optionaly, an extension for backup copies may be specified after dot. This parameter has to be the first one, if specified.
−−dir directory
Encoding files are taken from directory instead of the default, which is Cz/Cstocs/enc in the Perl lib tree. The location of encoding files can also be changed using the CSTOCSDIR environment variable, but the −−dir option has the highest priority.
−−fillstring string
If source text contains character, that is defined in the "src_encoding" but not in the "dst_encoding" nor in the accent file (or accent file is not used), it is replaced by "string". The default is single space.
−−nofillstring
Disable changes of characters that would otherwise have fillstring applied. This is different from "−−null" because that cancels that character out.
−−null
Completely equivalent to −−fillstring "".
−−nochange or −−noaccent
Do not use the accent file at all.
−−onebyone
Use only those rules from the accent file, which rewrite one character to one character. If this option is specified, character "ecaron" will be rewritten to "e", but " AE " character will not be rewritten to " AE " string.
−−onebymore
Use all rules from accent file. This is the default option.
