Hadn't imagined it would take regex elements...

The first two 

$encoded = encode_entities($input, '\W');
$encoded = encode_entities($input, '^\w');

wouldn't work for me. But I tried 
$encoded = encode_entities($input, '\\W'); # note double backslash

[download]
and that did work, with one little picky issue - it was encoding every whiteepsace char as well whic, while not technically bothersome, is just not needed.

So I tried the last formulation witha space added to list - had to add it as a simple typed space - wouldn't accept a \s: 

$encoded = encode_entities($input, '^a-zA-Z0-9_ ');

[download]
and that does it perfectly.

Thanks.
