<pre class="moz-quote-pre" wrap="">Hi Folks,
I read [1] that this is what case folding is:
Case folding is the process of making two texts which differ only in case identical for comparison purposes, that is, it is meant for the purpose of string matching.
I understand the use of the word "case," as in uppercase and lowercase.
I don't understand the use of the word "folding." Folding? Huh? I fold my towel. I fold my shirt. I don't fold my case (whatever that means).
Why is it called case "folding"? Who came up with that term?
