This is more a program logic question than Perl. I have many documents in a European language site, that users can search using a Perl CGI. The documents are Latin 1, and include special characters such as é, í, etc. Would it be more useful if a user could enter the plain character equivalent and still get results, for example, they enter "geosinteticos" and get documents with "geosintéticos"? Right now they can't. And, I do not know how to begin such a logic, by substituting in the search terms, when a term can contain more than one special character. How is this normally dealt with? I have not found any good examples.
