The Unicode/UCS2 values -for some of the RFC 1345 Mnemonic codes are out of date, -a cleanup and update would be needed for serious use. -[See also http://czyborra.com/charsets/iso8859.html for codepages survey.] - -These changes were made to all of the files used from ftp.unicode.org: - - a) add the MIME name of the charset. - b) add a name for the display charset (used on Options screen) - c) add the codepage number - d) remove lines for control characters 0x00 to 0x1f, 0x7f to 0x9f. - e) comment-out ASCII lines 0x20 to 0x7f - f) use idem to represent the commented-out lines - g) change C-style 0xNNNN constants to Unicode-style U+NNNN. - -Other changes include - - h) add code-points to several lines to provide Unicode equivalents - i) add extra mappings at the end of the files - j) comment-out other one-one mappings in the 0xa0-0xff range. - -More translation files can be easily provided (and new character entities -added to entities.h), this set is just to test whether the system works -in principle (and also how it behaves with incomplete data...) - -See the file README.format for a brief explanation of what's in the -table files. - -The examples have names *_uni or *_suni with a .tbl suffix, but it -doesn't really matter. The auxiliary program makeuctb (MAKE UniCode -TaBle) is used to "compile" them into C header files, which can be -included by UCdomap.c. - -Ideally, this should be taken care of by the Makefiles. On VMS, use -build-chrtrans.com to compile and link makeuctb.exe and create the -set of .h files from the current set of .tbl files. Thereafter, use -build-header.com to update particular .h files. - -To make a new chartrans table available to Lynx (and thereby make a new -charset known to Lynx) you currently have to manually edit UCdomap.c, in -two places: - -a) Near the top, you will find a bunch of lines (some may be commented out) - - #include "<fn>.h" - -Add or comment out as you wish. But it is probably safest to leave the -commonly used ones, referring to "def7_uni.h" and "iso01_uni.h", in place. - -b) At the bottom, you will find a bunch of lines (again, some may be - commented out by default) of the form - - UC_CHARSET_SETUP_<something>; - -which should correspond to the #include lines from a). Again, -add or subtract as you wish (but preferably consistent with what you -did under a)...) [The <something> is derived from the charset's MIME name. -if in doubt, check the last lines of the corresponding ...uni.h file.] - -c) To let make automatically notice when you have changed one of the - table files, and automatically regenerate the *uni.h file(s), -you also have to add any new tables to both src/Makefile *and* -src/chrtrans/Makefile. Or, for auto-config, the equivalent files -named makefile.in before running ./configure, or makefile after running -./configure. (That may be inconvenient, but I didn't want to depend -on features than not all makes may have.) Note that for recompiling -Lynx, a `make clean' should not be necessary if you have *only* made -changes to the files in src/chrtrans. On VMS, add entries for new -tables to build-chrtrans.com, but you can update the particular file -with build-header.com, then use the top directory's build.com and -answer 'n' to it's prompts about whether to update the WWWlibrary -and chrtrans modules. - |
