The dex format defined by Dalvik also uses the same modified UTF-8 to represent string values. [67] Tcl also uses the same modified UTF-8 [68] as Java for internal representation of Unicode data, but uses strict CESU-8 for external data.
The Universal Coded Character Set (UCS, Unicode) is a standard set of characters defined by the international standard ISO/IEC 10646, Information technology — Universal Coded Character Set (UCS) (plus amendments to that standard), which is the basis of many character encodings, improving as characters from previously unrepresented writing systems are added.
A character literal is a type of literal in programming for the representation of a single character's value within the source code of a computer program. Languages that have a dedicated character data type generally include character literals; these include C , C++ , Java , [ 1 ] and Visual Basic . [ 2 ]
ICU 72 updated to Unicode 15 (and 73.2 to latest 15.1). "In many formatting patterns, ASCII spaces are replaced with Unicode spaces (e.g., a "thin space")." ICU (ICU4J) now requires Java 8 but "Most of the ICU 72 library code should still work with Java 7 / Android API level 21, but we no longer test with Java 7."
Character literals char 'a', 'Z', '\u0231' (character or a character escape, enclosed in single quotes) Boolean literals boolean true, false: null literal null reference null: String literals String "Hello, World" (sequence of characters and character escapes enclosed in double quotes) Characters escapes in strings Unicode character
A string literal or anonymous string is a literal for a string value in the source code of a computer program. Modern programming languages commonly use a quoted sequence of characters, formally "bracketed delimiters", as in x = "foo", where , "foo" is a string literal with value foo. Methods such as escape sequences can be used to avoid the ...
In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text. The entity must either be predefined (built into the markup language) or explicitly declared in a Document Type Definition (DTD). The format is the same as for any entity reference: &name;
Unicode was designed to provide code-point-by-code-point round-trip format conversion to and from any preexisting character encodings, so that text files in older character sets can be converted to Unicode and then back and get back the same file, without employing context-dependent interpretation.
