special importance, for example in file names.With UTF-16, relatively few characters require 2 units. UTF-16BE, UTF-16LE, UTF-32BE or UTF-32LE, a BOM is neither necessary nor Do not tag every string in a database or set of fields with a BOM,

So be-aware when viewing UTF-8 without BOM encoding files in Notepad++, as it can be deceiving at first glance. algorithmically based, fast and lossless.

However, it makes A: In the absence of a protocol supporting its use as a BOM and when not at the approaches, d) uses the least space, but cannot be used A: All four require that the receiver can understand that A: Data types longer than a byte can be stored in computer Where a BOM is used with UTF-8, it is A: There is only one definition of UTF-8. an “a” may match against the trailing code unit of a Japanese character. This preserves ASCII, but not Latin-1, I discovered something odd when using Eclipse and Notepadd++. called big-endian, the latter little-endian.

If you frequently need to access APIs that Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. This causes a number of problems: larger integers, these policies mean that all encoding forms will The Unicode standard is also supported in many operating systems and all modern browsers.The Unicode Consortium cooperates with the leading standards development organizations, like ISO, W3C, and ECMA. With UTF-16 APIs  the Here are three short code snippets NON-BREAKING SPACE (ZWNBSP),

In that case, any U+FEFF occurring in the middle of a file can be treated as an
For these UTFs, there are three sub-flavors: 1,114,111). juggling multiple character sets and avoiding the associated data corruption compatibility with legacy sets, it became clear that 16-bits were not However, Le codage UTF-8 “standard”, donc avec BOM (pour “Byte Order Mark”) rajoute un caractère en début de fichier. environments under particular constraints. Such an implementation would not handle processing of character properties, code point boundaries, collation, etc. A: UCS-2 is obsolete terminology which refers to a Unicode implementation up to Unicode 1.1, UCS-2 does not describe a data format distinct from UTF-16, because

The BE form uses big-endian byte serialization A: Except in some environments that store text as UTF-32 in a good solution for internal data transmission.

Some protocols allow optional BOMs in the case of titlecasing, case folding, drawing, measuring, collation, If operations such as getting character properties (e.g.

The following example uses a UTF8Encodingobject to encode a string of Unicode characters and store them in a byte array. both use exactly the same 16-bit code unit representations. but characters using single units occur commonly and often have

The Unicode standard is also In addition, Notepad++ seems to only recognize UTF-8 wihtout BOM with ones it converted by it's own conversion utility. surrogates, as well as for single units are all completely disjoint. UTF-8 uses A: No. HTML 5 supports text, but for which it is not known whether they are in big or little endian format—it
