[Gambas-user] IsSpace error or bug?

[ron]

In wiki http://gambasdoc.org/help/lang/isspace

A space is one of the following characters: 
A space " ", 
A form-feed "\f", <--- not allowed !!!
A newline "\n", 
A carriage return "\r", 
A horizontal tab "\t", 
A vertical tab "\v".  <--- not allowed !!!

PRINT IsSpace(" \n \r\n")
True

PRINT IsSpace(" \n \r\f") <== \f should be space ??
I get "Bad character constant in string at...."
Same for \v
