Encoding
This page tracks notes related to the Encoding Standard. See Web Encodings for some historical data with respect to encodings and their labels.
Implementations
- http://code.google.com/p/stringencoding/ implements the standard in JavaScript
- http://darcsden.com/and/flex-encoding is an experimental (f)lex implementation of the decoding algorithms
Legacy implementations
- Gecko
- http://mxr.mozilla.org/mozilla-central/source/intl/uconv/
- Chromium
- http://src.chromium.org/svn/trunk/deps/third_party/icu46/README.chromium
- http://src.chromium.org/svn/trunk/deps/third_party/icu46/source/data/mappings/convrtrs.txt
- http://src.chromium.org/svn/trunk/deps/third_party/icu46/source/data/mappings/ucmlocal.mk

Sniffing
- http://www-archive.mozilla.org/projects/intl/UniversalCharsetDetection.html
- http://mxr.mozilla.org/mozilla-central/source/extensions/universalchardet/src/base/ (Gecko; tests are a few directories up)
- http://code.google.com/p/juniversalchardet/ (Gecko's detector in Java)
- https://bugzilla.mozilla.org/show_bug.cgi?id=631751 (UTF-16 sniffing in Gecko)
- http://trac.webkit.org/browser/trunk/Source/WebCore/loader/TextResourceDecoder.cpp (WebKit; is this all?)
Gecko notes
- Thai detection was not enabled before June 2009
- Encodings not in the spec: iso-2022-cn, euc-tw
- GB2312 is supported, but superset gbk/gb18030 is not
- UTF-16 sniffing is HTML specific
Misc
- XSS vulnerabilities with unusual character encodings
- Test multiple BOMs
