This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.
1 /* Test case for bug 340714
2 *
3 * Uses nsIConverterInputStream to decode UTF-16 text with all combinations
4 * of UTF-16BE and UTF-16LE with and without BOM.
5 *
6 * Sample text is: "Все счастливые семьи похожи друг на друга, каждая несчастливая семья несчастлива по-своему."
7 *
8 * The enclosing quotation marks are included in the sample text to test that
9 * UTF-16LE is recognized even when there is no BOM and the UTF-16LE decoder is
10 * not explicitly called. This only works when the first character of the text
11 * is an eight-bit character.
