Subject: Re: Substitution with Hash

Thanks that worked well, And no its not single chars, Which is the only 
reason i'm doing it this way..

I have to split on whitespace (/ /) because spliting on characters would 
obviously split the text i want to transform, which means it wont match 
if the characters are trailing another word, HTML special chars for 
example

h = {"&#126;" => "~"}

"hmm &#126;'.split(/ /).map{|c| h[c] || c}.join(' ')

Outputs hmm ~, but obviously doing things like question marks wont work, 
Maybe i'll have to use loops and string#tr
