Re: Foreign language chars as map keys

Thank you Rachel. I will look at employing     .charAt(0)     on the key. I
do believe it is indeed a string. To your point, I suspect I am comparing a
character to a string.
What of the need to clean up the keys - stripping them of any extraneous
spaces so I get just the character itself in the key string? Anyone know a
way to work through the map and trim keys?
