Syntax for Tab and Enter keys

Syntax for Tab and Enter keys

Hi:

In a Multi Line field a user can press the Tab and Enter keys.

I would like to know how one references these "invisible' characters inside such a field with Deluge commands like ...

<string>.getPrefix(<substring>)

... is there some special syntax that can be used to define such characters for <substring> ... like "\t" or "\n" or "&#09" or "&#10" etc. ?

In one of my projects, I need to parse entered values separated by spaces ... but users might mistakenly type Tab or Enter keys ... so I want to replace such characters with space characters before doing the parse function.
