Not sure about 'easier', let alone 'faster' (I'm sure it isn't), but it 
is 40% shorter, to ~48 chars (choose the token wisely):

tokenize(replace('Kibology', '(.)', '$1~'), '~')

Wannabe sure of the token not being in your string, use Private Use Area 
characters:

tokenize(replace('Kibology', '(.)', '$1'), '')

but this doubtlessly makes it less readable and a bit larger ;)
