Note: many top sites for Hong Kong are the same as mainlaind China, typically video sites.

Note: ranking are by domain. For example, “tw.yahoo.com” is globally ranked 4, but that ranking is for the whole domain “yahoo.com”, not just the subdomain “tw.yahoo.com”.

Japan Sites

[fc2.com](blog, web hosting, etc)UTF-8#53
[www.rakuten.co.jp]楽天市場 (shopping)EUC-JP, UTF-8#74
[www.livedoor.com](portal)UTF-8 #106
[goo.ne.jp](search; portal)UTF-8, EUC-JP#146

Many Japan sites seem to use both UTF-8 and EUC-JP. Home page uses one, but many pages uses the other.

Note: many top sites for South Korea are the same as mainland China.

India Sites

Top 200 sites in India are all English. Vast majority are just normal USA sites, for example, Yahoo, Twitter, MSN, etc. (Note: the official language for India is English and Hindi, but English is practically the language for all business and science.)

Intro to Chinese Encoding

Here's a summary of major Chinese encoding:

year . Simplified Characters only. Was used in mainland China.
year . Extended GB2312. Includes traditional chars.
year . Extended both GB2312 and GBK. Charset equivalent to Unicode. Contains both simplified and traditional characters. Used in mainland China.
year . Traditional chars only. Invented and used in Taiwan, before Unicode became popular.

[see 简体繁體字表 List of Simplified/Traditional Chinese Characters]


Taiwan sites almost all use UTF-8. Very old ones still use BIG5.

Mainland China sites mostly still use GBK or GB2312, but a few newer ones use UTF-8.

Many top Japan, Korea, sites also use UTF-8, but some uses EUC ([ Extended Unix Code ] [ https://en.wikipedia.org/wiki/Extended_Unix_Code ]) variants.

This probably means that UTF-8 might dominate in the future.
