* Silly of me to overlook it: another obvious way you might like toSimon Tatham2012-07-19
| | | | | | | | | specify characters to 'confuse' is to just put them on the command line in the system multibyte encoding! In a UTF-8 terminal environment this may very well be the easiest thing. [originally from svn r9584] [this svn revision also touched charset,filter,timber]
* A slightly silly new utility: 'confuse'. You provide it with someSimon Tatham2012-07-18
| | | | | | | | | | | | | Unicode values (typically two of them), and it finds cases in which the provided characters are all encoded as the same thing in different charsets and prints those charsets. So if you encounter, for example, some piece of text which has U+0153 LATIN SMALL LIGATURE OE where you might have expected U+00A3 POUND SIGN, simply run 'confuse 153 a3' and it'll tell you which character sets the sender and receiver of the text might have got confused between.

* Correct a comment.Simon Tatham2011-11-09
| | | | | | | | | | | | | | | I had wrongly believed my TYPECHECK macro double-evaluated one of its arguments and hence would cause side effects to happen twice. But in fact I've just realised that although it double-_expands_ the argument, it doesn't double-_evaluate_ it: the two expansions occur in mutually exclusive branches of a ?:, and hence cannot both be executed. So I've removed the comment that says my macro is rubbish. My macro is in fact great :-) [originally from svn r9328] [this svn revision also touched charset,filter,timber]

* Add a mechanism for translating to and from the coding system symbolsBen Harris2007-04-09

* I've apparently had this lying around for months but forgotten toSimon Tatham2006-06-13
| | | | | | | | | commit it. Add `-i' option to cstable, which causes charset names to be output as CS_* constants where meaningful. (Doesn't apply to MBCS base charsets, because CS_* constants identify _encodings_.) [originally from svn r6728] [this svn revision also touched charset,filter,timber]

* sbcsgen.pl was giving different results on different machines in the caseJacob Nevins2006-04-26
| | | | | | | | | | | where two SBCS code points mapped to a single Unicode point. Changed so that by default it favours the lower SBCS code point. On ixion, this highlighted ambiguities in CS_MAC_THAI, CS_MAC_SYMBOL, and CS_VISCII. Guessed at a preference for the first two and added "sortpriority" directives. (No idea about VISCII.)

* CP866 is popular and small. Add it to both the general and PuTTYJacob Nevins2005-12-18

| | | | | | | | | genuinely portable form. (Thanks to IWJ for ideas.) While I'm here, add a couple of explicit `unsigned' casts and U suffixes to prevent more pedantic compilers from warning. [originally from svn r6463] [this svn revision also touched charset,filter,timber]
* Fix various compiler warnings and errors. In particular, my cunningSimon Tatham2005-11-13
| | | | | | | | auto-type-checking DEPLANARISE and REPLANARISE macros have turned out to only work in gcc, which is a shame. [originally from svn r6455] [this svn revision also touched charset,filter,timber]
* write_utf8() is used in iso2022.c as of r6378; declare it.Jacob Nevins2005-10-23

* Working ISO 2022 output function. Outputs full ISO 2022 (not sureSimon Tatham2005-10-07
| | | | | | | | | | | | | | | what that's useful for but it seemed a pity not to do it) and compound text. I've completely removed the compound text implementation from iso2022s.c in favour of using the more flexible iso2022.c, meaning we can cope with nastiness such as DOCS. This is largely untested: I've checked it on small examples as I went along, but it lacks anything resembling a proper test suite.

* Space-saving restructure of the CNS 11643 data tables. Reduces theSimon Tatham2005-09-24
| | | | | | | | | | | | | | | RO data size in cns11643.o from 400k to 240k. Relies on there being at most seven planes (7*94*94 <= 64k) and on the character set not encoding any Unicode code point above U+40000; if either of these becomes untrue later on we can always fall back to the previous approach, or to somewhere between that and here. The new version passes all the same tests as the old one did, and generates the same output under the new `cstable -v'. I'm confident that I haven't broken it.
