There are two types of file character sets in Windows: ANSI and Unicode.For Unicode, Windows supports three of its encoding methods: Small Tail encoding (UNICODE), big tail encoding (bigendianunicode), and UTF-8 encoding.We can identify the encoding of a file from its header. When the first two bytes of the header are FF Fe, the Unicode tail encoding is used. When the first two bytes are Fe ff, the Unicode tail encoding is used; when the two bytes in the header are ef bb, It is the Unicode UTF-8

Title:You is given a string, s, and a list of words, words, that is all of the same length. Find all starting indices of substring (s) in s that's a concatenation of each word in wordsexactly once And without any intervening characters.for example, given:s : " Barfoothefoobarman " words : [" foo "," Bar "] You should return the indices: [0,9] .(Order does not matter).Test Instructions:Given a string s, and a set of string array words, all string lengths in the array are the same.

Recently, Asp-related files cannot be found on the Internet. If someone gets it out early, don't joke about it. After a long time, you can get it done; Principle: Analyze and determine the UTF-8, Unicode, and ANSI (Simplified Chinese operating system (gb2312) encoding by using the first two bytes of the stream object pre-Read File. Related Materials: Supplement: Xie Xiaoyu reminded me that the previous code is nonsense. ANSI's local code is defined by countries and does not have a fix
