Hey Tab,
I grepped over my corpus of the JS from the top 64,621 domains (from
Alexa's top 1 million list) for "CHARSET_RULE", "CSSCharsetRule" and
".encoding". Here's the results:
mtaylor at omg-2 in ~/Desktop/8449206 on master
$ cat CSSCharsetRule.txt | wc -l
1
mtaylor at omg-2 in ~/Desktop/8449206 on master
$ cat CHARSET_RULE.txt | wc -l
15
mtaylor at omg-2 in ~/Desktop/8449206 on master
$ cat dot-encoding.txt | wc -l
3068
You can clone the gist here if you want to inspect the full details
yourself: https://gist.github.com/miketaylr/8449206 (the results for
".encoding" are quite large, some lines contain entire JS libs that have
been minfied/concatted).
later,
