Weak points:
- alignof
- js problems
Todo:
- make js work with C++ and mozjs-17
- then mozjs-24

- decrease number of warnings
Make u2cp_() map code points U+0080 to U+009F via strange_chars[] even
if the target codepage is UTF-8. This helps with buggy web pages that
use ’ when they mean ’. This change does not affect how
ELinks decodes raw bytes 0x80 to 0x9F in HTML.
u2cp_() is used only via the u2cp and u2cp_no_nbsp macros.
Possible side effects of this change at each use of these macros:
* get_translation_table(): Not affected because it does not call u2cp
if the target codepage is UTF-8.
* get_entity_string(): Numeric character references are affected, as intended.
Character entity references are not affected because entities[]
does not define any entities in the U+0080...U+009F range.
* kbd_field(), term_send_ucs(), field_op(): Affected. It is no longer
possible to enter code points U+0080...U+009F from the terminal.
This should not be a problem in practice because those would be
control characters anyway and should therefore be filtered by the
slave process (which doesn't yet recognize them; bug 777).
After viewing a page with Big5 charset and next a page with UTF-8
charset iconv was used, so slows down a bit.
Now iconv is used only for those charsets, which has the iconv
bitfield set.
I am not hooking these to "make test", for two reasons:
1. utf8_step_forward is inside #ifdef CONFIG_UTF8 and I don't see
how to make tests conditional on such options.
2. test/libtest.sh was copied from Git, which is under GPLv2-only.
Adding more dependencies on it could make ELinks more difficult
to relicense under GPLv2-or-later.
This check used to be in src/elinks.h. Move it to configure.in so
that (1) the result can be logged and (2) ELinks won't even link with
TRE if wchar_t prevents its use.
Also, rename HAVE_TRE_REGEX_H to CONFIG_TRE, to reflect that it is not
always defined if the header exists.
C99 6.7.4p3 and 6.7.4p6 set some constraints on what can be done in
inline functions and how they can be declared. In particular, any
function declared inline must also be defined in the same translation
unit. To comply with that, remove inline specifiers from function
declarations in header files when the functions are not also defined
in those header files.
Sun Studio 11 on Solaris 9 is stricter than C99 and does not allow
references to static identifiers in extern inline functions. Make the
configure script detect this and define NONSTATIC_INLINE accordingly
in config.h. Then use that in the definitions of all non-static
inline functions.
Document the restrictions and this scheme in doc/hacking.txt.
When the file is being read, Expat provides the strings to ELinks in
UTF-8, so ELinks can put them in struct bookmark without conversions.
Make sure gettext returns any placeholder strings in UTF-8, too.
Replace '\r' with ' ' in bookmark titles and URLs.
When the file is being written, put encoding="UTF-8" in the XML
declaration, and then write out the strings from struct bookmark
without character set conversions. Do replace some characters
with entity references though, by calling add_html_to_string().
This simplifies the callers a little and may help implement
simultaneous support for different charsets on different terminals
of the same type (bug 1064).
In get_entity_string and point_intersect, do not initialise arrays with
static storage duration to zero; the C standard states that such objects
are automatically initialised to zero.
Add #include directives to fix these errors:

Bug 932 is about ELinks letting control characters 0x80...0x9F through
to the terminal. It did not occur with ISO 8859-1, 8859-2, 8859-15,
or 8859-16, because the ELinks mappings for those charsets did not
include those bytes. However, the www.unicode.org versions imported
in the previous commit do include the problematic bytes.
To avoid a possible regression before the ELinks 0.12.0 release,
comment those control-character mappings out again. This workaround
should be reverted after bug 932 has been fixed properly.
Add copyright and licence notices, and a NEWS entry.
The data in the new versions is not entirely the same as what ELinks
used to have:
- Unicode/8859_1.cp: Adds control characters.
- Unicode/8859_2.cp: Adds control characters.
- Unicode/8859_4.cp: Adds some control characters that ELinks assumed
there already.
- Unicode/8859_7.cp: Adds three characters.
- Unicode/8859_15.cp: Adds control characters.
- Unicode/8859_16.cp: Adds control characters and swaps 0xA5 with 0xAB.
- Unicode/koi8_r.cp: Changes 0x95 and adds some control characters
that ELinks assumed there already.
- Unicode/macroman.cp: Changes 0xC6 and removes some control characters
that ELinks assumes there anyway.
