/* Test case for bug 340714
|
||
*
|
||
* Uses nsIConverterInputStream to decode UTF-16 text with all combinations
|
||
* of UTF-16BE and UTF-16LE with and without BOM.
|
||
*
|
||
* Sample text is: "Все счастливые семьи похожи друг на друга, каждая несчастливая семья несчастлива по-своему."
|
||
*
|
||
* The enclosing quotation marks are included in the sample text to test that
|
||
* UTF-16LE is recognized even when there is no BOM and the UTF-16LE decoder is
|
||
* not explicitly called. This only works when the first character of the text
|
||
* is an eight-bit character.
