For example, an English speaker typically wants "San Jose" to also match "San José", especially when he doesn't know how to type accented characters. For a French speaker, on the other hand, "ne" and "né" are distinct words. Japanese speakers sometimes want to treat all of "あ", "ぁ", "ア", "ア", and "ァ" as similar, or even better, have "たなか" match "田中" based on pronunciation. And in pretty much all cases you want to apply Unicode normalization.

Biju: I could accept that argumnet

> For use cases where you want to select a subset of a list of strings based on similarity, Collator objects from the ECMAScript Internationalization API can be used, with the usage option set to "search". But for the use cases you're primarily concerned about, new API will be needed. Since this is all language and context sensitive, the ECMAScript Language Specification is probably not the right place to define this API.

Biju: Then let me redefine my request. Instead of "Ignore case", match
text by what ever satisfying "i" flag for RegExp  defined in ECMA
script/the browser/user agent. Dont tell me now there is nothing
defined for "i" flag.

Also nothing above is stopping standardization of mozilla non-standard
flags parameter for String.replace as standard.
