[zh-TW] Set default value of intl
.charset .default to UTF-8 and turn on Universal Charset Detector
Everything is ready, just need to explain things here for the record. intl.charset.default affects a) The request header "Accept-Charset" b) The encoding text files or web pages if it does not specific its encoding, which is really rare now days. By changing the value from Big5 to UTF-8, we could 1) keep some of the mis-configured servers to behavior in the same way with en-US browser, even if it erroneously "obeys" Accept-Charset header. 2) keep the browser behavior in the same way with en-US version when it encounters a UTF-8 plain text file. To minimize impact, the change would also turn on Universal Charset Detector (see ref), which is a piece of decade old code that guesses the encoding of these legacy pages that fits condition (b). The reason I choose Universal over zh-TW one is because over the years, the usage of zh-CN websites in Taiwan had grown rapidly and they don't really obeys web standards most of the time. I've already asked our beta users to test out the new configure values, so far none of them have feel any difference. The changes would apply to existing profiles - I think it's better to ship the change in a new version, i.e. Firefox 3.6. ref: http://www.mozilla.org/projects/intl/chardet.html see also (forum discussion in Chinese): http://forum.moztw.org/viewtopic.php?f=4&t=28987 Tim

Simon, does switching on the universal charset detector come with a perf cost?
It can cause bug 61363, which is annoying, but other than that I don't think the perf cost is serious. Instead of "Universal", I would consider the option of "Chinese", which will detect both Simplified and Traditional (and Latin-1 and UTF- encodings), but won't activate the other detector modules.
