/* 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.
