Recognize all of 
 
 with any number of leading
zeroes. (Previously only and 
 were supported.) All of
these are case insensitive.
Treat each CR+LF combination ( ) as a single newline.
The configure script no longer recognizes "CONFIG_UTF_8=yes" lines
in custom features.conf files. They will have to be changed to
"CONFIG_UTF8=yes". This incompatibility was deemed acceptable
because no released version of ELinks supports CONFIG_UTF_8.
The --enable-utf-8 option was not renamed.
Suggested by Miciah on #elinks.
What was renamed:
add_utf_8 => add_utf8
cp2utf_8 => cp2utf8
encode_utf_8 => encode_utf8
get_translation_table_to_utf_8 => get_translation_table_to_utf8
goto invalid_utf_8_start_byte => goto invalid_utf8_start_byte
goto utf_8 => goto utf8
goto utf_8_select => goto utf8_select
terminal_interlink.utf_8 => terminal_interlink.utf8
utf_8_to_unicode => utf8_to_unicode
What was not renamed:
terminal._template_.utf_8_io option, TERM_OPT_UTF_8_IO
Compatibility with existing elinks.conf files would require an alias.
--enable-utf-8
Because the name of the charset is UTF-8, --enable-utf-8 looks better
than --enable-utf8.
CONFIG_UTF_8
Will be renamed in a later commit.
Unicode/utf_8.cp, table_utf_8, aliases_utf_8
Will be renamed in a later commit.
Surrogates are now treated the same way as out-of-range characters
like U+110000; if a link has such an access key, then the ECMAScript
accessKey property cannot be read. It seems currently impossible to
set such an access key though, because accesskey_string_to_unicode()
doesn't support multibyte characters yet.
Drop some code for superscript and subscript handling that was deleted
in commit 65016cdca4, then added back
with the UTF-8 merge in commit 2a6125e3d0,
and then disabled in commit 1b653b9765.
Commit 3ce3f01f30 introduced a bug whereby
if a tab set the current position in the line to or greater than the number
of bytes remaining in the source, the line was split after the tab.
Its return value is now an enum that lets callers know whether an
error occurred. However, this commit changes the callers only
minimally, so they do not yet check the return value.
In html_subscript, html_subscript_close, html_superscript, html_quote, and
html_quote_close, use put_chrs instead of html_context->put_chars_f.
Element handlers should use put_chrs so that it can correctly handle
whitespace and stuff.
