Thanks James!


I have narrowed the chars you should delete after transliteration.  If  
you try with the ~full range of accented latin chars


require "iconv"

ss=  
"ÀÁÂÃÄÅĀĄĂÆÇĆČĊĎĐÈÉÊËĒĘĚĔĖĜĞĠĢĤĦÌÍÎÏĪĨĬĮİIJĴĶŁĽĹĻĿÑŃŇŅŊÒÓÔÕÖØŌŐŎŒŔŘŖŚŠŞŜȘŤŢŦȚÙÚÛÜŪŮŰŬŨŲŴÝŶŸŹŽŻàáâãäåāąăæçćĉċďđèéêëēęěĕėƒĝğġģĥħìíîïīĩĭįıijĵķĸłľĺļŀñńňņʼnòóôõöøōőŏœŕřŗśšşŝșťţŧțùúûüūůűŭũųŵÿŷžżźþßſÐð 
"

# you can see a small set of chars that are used to transliterate: "'~^`

   puts Iconv.conv("ASCII//TRANSLIT//IGNORE", "UTF-8",  
ss).delete(%q{"'~^`})



This is a less aggressive way of patching this annoying behaviour of  
transliterate.  I would like to see new //CLEANDROP  or so, to simply  
drop out those accents to work with the chars.  Or simply a regexp  
search with a modifier that could make it just to ignore accents…
