Thank you, I like this patch a lot!

> +	   - Uses windows-949 and windows-874 instead of windows-949-2000 and
windows-874

A typo, should be windows-874-2000.

The reason why I used windows-949-2000 is that windows-949 is ambiguous in ICU,
see <http://demo.icu-project.org/icu-bin/convexp?s=IANA&s=MIME&s=ALL>. Does
anything guarantee that the correct codec will be picked for windows-949 family
encodings with your change? I _think_ that windows-949-2000 is the correct one,
as in matching WinIE better, but I haven't verified that assumption. This is
not an issue for windows-874.

On a tangential note, HTML5 uses the windows-949 name:
<http://www.whatwg.org/specs/web-apps/current-work/#character-encoding-requirem
ents>.

> +	   - Maps 'dos-874' to 'windows-874'

Could you please mention the rationale, in this bug and/or in ChangeLog? Is
this done for compatibility with other browsers? Do both Firefox and IE support
this name? Do we have a reason to think that actual pages ever use it? I don't
have anything against this change, just want it fully documented.

> +	   - Maps 'EUC-CN' to 'GBK' and replaces it with 'GBK' when it's used
as the canonical name

Is this a change in behavior? According to ICU converter explorer, EUC-CN is
already mapped to GB2312, which we upgrade to GBK.

> +	   - Adds 'x-uhc' as an alias for 'windows-949'

Could you please mention the rationale?

r- because of the concern about ambiguity of windows-949, but please feel free
to mark for review again if it's actually OK for some reason that I missed.
