Small Strings

[etm]

CharlockHolmes::EncodingDetector.detect_all("Timeout: 2")

results in

{:type=>:text, :encoding=>"IBM424_ltr", :ruby_encoding=>"binary", :confidence=>27, :language=>"he"},
{:type=>:text, :encoding=>"UTF-8", :ruby_encoding=>"UTF-8", :confidence=>15},
....

in general it seems to try too hard for small strings. for small strings it often favors esoteric (wrong) results over obvious ones.
is it possible to tweak this? is this intended?
