How to add a new output character encoding to wv ================================================ The reason that utf-8 is used for output in 90% of cases is that word itself usually stores documents in 16bit unicode. In ascii languages it often uses the windows codepages. When the text is 8 bit and uses the western european codepage 1252 then we have a special case and we output by default iso-5589-15. If it is a different 8 bit codepage we convert it to unicode through one of the unicode mapping tables and then output utf-8 from this. When the document is in unicode or has been converted up to unicode it is easiest to convert it to utf-8 html which netscape can display. It *is* possible to add different conversions. Ill walk through the issues involved in this. There exists a call on some unices called iconv which is for conversion of charsets. The glibc2 one can handle windows codepages. But other platforms such as solaris have iconv but its a useless implementation, so wv does the following. tests on configure for the existance of iconv, and test if it can handle the windows codepages that I am currently supporting. If it does (it appears that only glibc2 fits this profile) then we use that for our windows codepage to unicode conversion, if it does not then I have a mini iconv implementation which can only handle windows codepage into unicode conversion, unicode into utf, unicode into koi8-r, unicode into iso-8859-15 and unicode into tis-620 (thai). If you want to convert to a different output language try wvHtml --charset nameofcharset file.doc If you have a good iconv implementation on your system then it will work. If you have a useless iconv and I have had to substitite my own mini iconv implementation then you can do the following... Add a new file for your conversion to the iconv dir, add the filename to the iconv/Makefile.in *AND* to the wv Makefile.in. Follow the pattern of a converter such as the koi8-r.c. It would be nice if you included a document which used the language you are supporting to this dir, as well as a screenshot of what it should look like so that I can confirm in the future that any changes I might have made have not broken the converter. You will have to implement a unicode (16bit varient) to your charset, add your converer to 1) iconv_internal.h 2) all the appropiate Makefiles are mentioned before 3) to the convertt outputs structure in iconv.c, bump up the NOOUTPUTS define by one. Make sure you use the correct name for the charset name in the other convertt field. 4) Test it. C.
