# Constants
Constants define how the parser treats documents. They can be defined before
loading the parser to globally replace the default values.
## DEFAULT_TARGET_CHARSET
Defines the default target charset for text returned by the parser.
Default: `'UTF-8'`
## DEFAULT_BR_TEXT
Defines the default text to return for `
` elements.
Default: `"\r\n"`
## DEFAULT_SPAN_TEXT
Defines the default text to return for `` elements.
Default: `' '`
## MAX_FILE_SIZE
Defines the maximum number of bytes the parser can load into memory. This limit
only applies to the source file or string.
Default: `600000`
