All,

Does anybody know of any study that has investigated
the visual similarity of computer language punctuators
and operators?  For instance, how visually similar is ( to
O and l, and so on...

The studies by Kuennapas ("Visual perception of capital letters"
and "Multidimensional similarity of letters") deal with upper
and lower case letters (Swedish) only.

The OCR literature treats it as a machine learning issue.  The
Kuennapas studies asked people for their views on the visual
similarity.  Perhaps these should deliver the same final result,
but I am not convinced.
