∟Big5 Usage Trends

Usage Big5 on Web sites dropped from 3.5% in 2010 to 1.0% in 2015, as more and more Web sites are using UTF8 now.

An interesting report, "Historical yearly trends in the usage of character encodings for websites" at w3techs.com/technologies/history_overview/character_encoding/ms/y shows the usage trend of Big5 on Web sites together with GBK and other encodings:

As you can see from the report, more and more Web sites are using UTF-8 (the standard Unicode Encoding) now, jumping from 50.6% in 2010 to 92.8% in 2019. At the same time, less and less Web sites are using Big5, dropping from 0.4% in 2010 to 0.1% in 2019.

So from the Web site point of view, usage of Big5 will soon become history.
