the variable-length UTF-16 needed to support all emoji characters, the SMS standard specifies its predecessor fixed-width UCS-2 which do not support most of them). The Web Hypertext Application Technology Working Group (WHATWG) considers UTF-8 "the mandatory encoding for all " and that for security reasons browser applications should not use UTF-16. UTF-8, by comparison, accounts for 98% of all web pages. UTF-16 is the only web-encoding incompatible with ASCII and never gained popularity on the web, where it is used by under 0.002% (little over 1 thousandth of 1 percent) of web pages. Since May 2019, Microsoft has begun supporting UTF-8 (as well as UTF-16) and encouraging its use. It is rarely used for files on Unix-like systems. It is also sometimes used for plain text and word-processing data files on Microsoft Windows. UTF-16 is used by systems such as the Microsoft Windows API, the Java programming language and JavaScript/ECMAScript. UTF-16 arose from an earlier obsolete fixed-width 16-bit encoding, now known as UCS-2 (for 2-byte Universal Character Set), once it became clear that more than 2 16 (65,536) code points were needed.
The encoding is variable-length, as code points are encoded with one or two 16-bit code units. There should be no need to handle any magic strings to specify character set names in your code.UTF-16 ( 16-bit Unicode Transformation Format) is a character encoding capable of encoding all 1,112,064 valid code points of Unicode (in fact this number of code points is dictated by the design of UTF-16). In this example we read all the lines in a file and we can use the StandardCharsets class here too. Other parts of the standard API allow this as well. It looked like this: public enum Charsets įinal String test = new String(bytes, StandardCharsets.UTF_8) Historyīack in 2012 I still used a little helper enum called Charsets that had values for different standard character sets that I may need. Let’s have a look at a solution to use character set strings like “UTF-8” in your code without placing these strings everywhere.
