Re: [elinks-users] Displaying Big5 Charset

Dear Mr. Masters,

Miciah Dashiel Butler Masters wrote on 13 Jul 2010:

 ELinks does not support Big5 (or GB2312).  There is a report on
 Bugzilla, should use iconv for charset that it doesn't know:

 http://bugzilla.elinks.cz/show_bug.cgi?id=891

 It would be wonderful if somebody implemented that (and it has been
 discussed several times), but it would be a good amount of work.


Thank you for clarifying that. I am not much of a programmer, so doubt
that I would be able to add the iconv functionality by myself.
However, as far as individual charsets are concerned, is there much
more to getting them to work than providing translations tables to
UTF-8, like the ones in Unicode directory in elinks sources?

Both tables seem to be available from Unicode Consortium to some
degree at least (using Microsoft's CP936 for GB2312 and CP950 for
Big5):

[elinks-users] Displaying Big5 Charset

[Richard R. Boyechko]

Dear Elinkers,

I have been using elinks for several years for an occasional web
browsing when X is not available, but over the past couple of weeks
have switched to using elinks almost exclusively for all my browsing
needs. As part of that, I am trying to view a Big5-encoded website
[1]. Try as I may, however, I cannot get it to display anything but
gibberish. Could anyone help me figure out what I'm doing wrong, or at
least unequivocally say that it's not supported and won't work?

Here's what /should/ be displayed:

Here's what is actually displayed:

I tried changing LC_CTYPE variable (as well as LC_ALL, just to test
things out) to zh_TW.Big5, but the results weren't very promising
either:

Any help would be greatly appreciated.
