/**
|
|||
|
|
* Character codes.
|
|||
|
|
*
|
|||
|
|
* This module is compiled away!
|
|||
|
|
*
|
|||
|
|
* micromark works based on character codes.
|
|||
|
|
* This module contains constants for the ASCII block and the replacement
|
|||
|
|
* character.
|
|||
|
|
* A couple of them are handled in a special way, such as the line endings
|
|||
|
|
* (CR, LF, and CR+LF, commonly known as end-of-line: EOLs), the tab (horizontal
|
|||
|
|
* tab) and its expansion based on what column it’s at (virtual space),
|
|||
|
|
* and the end-of-file (eof) character.
|
|||
|
|
* As values are preprocessed before handling them, the actual characters LF,
|
|||
|
|
* CR, HT, and NUL (which is present as the replacement character), are
|
|||
|
|
* guaranteed to not exist.
|
|||
|
|
*
|
|||
|
|
* Unicode basic latin block.
