To support specified character encoding, the editor must be able to load, save, view and edit text in the specific encoding and not destroy any characters. For UTF-8 and UTF-16, this requires internal 16-bit character support. Partial support is indicated if: 1) the editor can only convert the character encoding to internal (8-bit) format for ...
For processing, a format should be easy to search, truncate, and generally process safely. [citation needed] All normal Unicode encodings use some form of fixed size code unit. Depending on the format and the code point to be encoded, one or more of these code units will represent a Unicode code point. To allow easy searching and truncation, a ...
Punycode, another encoding form, enables the encoding of Unicode strings into the limited character set supported by the ASCII-based Domain Name System (DNS). The encoding is used as part of IDNA, which is a system enabling the use of Internationalized Domain Names in all scripts that are supported by Unicode.
^ The current default format is binary. ^ The "classic" format is plain text, and an XML format is also supported. ^ Theoretically possible due to abstraction, but no implementation is included. ^ The primary format is binary, but text and JSON formats are available. [8] [9]
Unicode is an effort to include all characters from all currently and historically used human languages into single character enumeration (effectively one large single code page), removing the need to distinguish between different code pages when handling digitally stored text.
A numeric character reference in HTML refers to a character by its Universal Character Set/Unicode code point, and uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form. The x must be lowercase in XML documents.
When opened by a text editor, human-readable content is presented to the user. This often consists of the file's plain text visible to the user. Depending on the application, control codes may be rendered either as literal instructions acted upon by the editor, or as visible escape characters that can be edited as plain text. Though there may ...
A CCSID (coded character set identifier) is a 16-bit number that represents a particular encoding of a specific code page.For example, Unicode is a code page that has several character encoding schemes (referred to as "transformation formats")—including UTF-8, UTF-16 and UTF-32—but which may or may not actually be accompanied by a CCSID number to indicate that this encoding is being used.
