whitespace_trim

Values 

on|yes|true or off|no|false or leading|trailing

The default value is on

Description 

A whitespace is any character or series of characters that represent horizontal or vertical space in typography. When rendered, a whitespace character is not a visible mark, but does occupy an area or space on a page.

Although whitespaces are necessary within a string (typically to separate words), unnecessary whitespaces can be found at the start of a string (leading) and at the end of a string (trailing).

With this directive, you can trim whitespaces, as it enables or disables whitespace trim management for the ingested strings.

By default, the leading and trailing whitespaces are trimmed.

You can choose to disable trimming or specify trimming for leading or trailing whitespaces.

The directive can be used inline or as the API request parameter.

Examples 

smartling.whitespace_trim=on

Smartling will trim leading and trailing whitespaces (default)

smartling.whitespace_trim=off

Smartling will not trim leading or trailing whitespaces

smartling.whitespace_trim=leading

Smartling will trim only leading whitespaces

smartling.whitespace_trim=trailing

Smartling will trim only trailing whitespaces
