^^ The portion of the byte that stores the 61 is the lower value portion which with LE is stored first.

And a good way to see what notepad or whatever software is doing, is by looking at the hex of a file C:\asdf>notepad.exe a.aĪ.a Little-endian UTF-16 Unicode text, with no line terminatorsĠ000000: fffe 6100 6100 6100 6161 610d. But choose a unicode font like arial unicode, and copy in some unicode characters from charmap and it will. Sometimes you can tell notepad to save as unicode(by which notepad means unicode 16 bit little endian), and it won't. What UTF-8 is (and UTF-8 can be with or without a BOM). Then you actually see what UTF 16bit LE is. Use the 'file' command to help identify a file. Get Cygwin and xxd, and/or a hex editor and look at what is really inside the file. To really see the differences know the Software, what Encoding a piece of software uses or offers. It wouldn't be a very flexible OS if there was. There is no one rule of what Unicode encoding a particular OS uses.

What Unicode encoding is used is not OS based.Įven Windows notepad.exe has options listed- (i'll put in brackets what notepad means by that)ĪNSI(not unicode), Unicode(notepad means Unicode LE), Unicode Big Endian(BE), UTF-8ĪNSI isn't unicode it involves a very limited number of characters so lets put that aside.īut see even notepad can do LE, or BE, or UTF-8Īnd notepad aside, UTF-8 can be with or without a BOM.Īnd I use Windows with Cygwin though Windows ports may well do \r\n even when you specify \n Have seen sed do that.

Plus, it'd be pointless to have a UTF-8 signature when UTF-8 is the default encoding anyway. On Linux, the BOM is discouraged because it breaks things like shebang lines in shell scripts. On Windows, UTF-8 files often start with a "byte order mark" EF BB BF to distinguish them from ANSI files. U+FEFF ZERO WITH NO-BREAK SPACE (Byte-Order Mark)

For example, if you type a file at the command prompt, it will be truncated at the first 1A byte. Windows (rarely) uses Ctrl+ Z as an end-of-file character. Problematic Special Characters U+001A SUBSTITUTE Fortunately, Notepad is capable of reading UTF-8 files unfortunately, "ANSI" encoding is still the default.

It internally works in UTF-16, and assumes that char-based strings are in a legacy code page. Windows, however, lacks native support for UTF-8. Most modern (i.e., since 2004 or so) Unix-like systems make UTF-8 the default character encoding. Windows uses CRLF ( \r\n, 0D 0A) line endings while Unix just uses LF ( \n, 0A).
