The Unicode standard divides the space of all possible code points in planes a plane is a range of 65,536 (1000016) contiguous Unicode code points. In these cases a single "character" may be mapped to more than one code point or vice versa more than one character may be mapped to a single code point. Note that typically one character is assigned exactly one code point, but there are exceptions the so-called precomposed characters (see ) or the ligatures. Unicode assigns each character of almost any existing alphabet/script a number, which is called code point it's typically indicated in documentation manuals and in the Unicode website as U+xxxx where xxxx is an hexadecimal number. some of the possible glyphs for the capital letter 'A' are: Any character may have one or more glyph associated e.g. When working with Unicode, it's important to define the meaning of some terms.Ī glyph is a particular image (usually part of a font) that represents a character or part of a character. Moreover, any application reading files which it didn't produce or receiving data from the network from other services should be ready to deal with Unicode. įrom a practical point of view, using Unicode is almost a requirement when writing applications for international audience. More details about Unicode may be found at. This allows enough code points (see below for the definition) sufficient to encode all of the world languages at once. the ASCII standard), by using 8, 16 or 32 bits for encoding each character. Unicode is a standard for character encoding which addresses the shortcomings of the previous standards (e.g. You can skip the first two sections if you're already familiar with Unicode and wish to jump directly in the details of its support in the library. Please see Unicode-related Changes for the details of these changes. Notice that Unicode support has changed radically in wxWidgets 3.0 and a lot of existing material pertaining to the previous versions of the library is not correct any more. This section describes how does wxWidgets support Unicode and how can it affect your programs.
