How can I use ASCII Characters on the iPad?

For those characters you will have to use copy/paste for now.

However, if you are using a word processor like Pages with Find and Replace capabilities a way to simplfy this process is to type a unique character or character string for each of your special characters and then later do a Replace All of these which what you want.

For example:

>= for ≥

<= for ≤

tm for ®

etc.

I think you will have to use an app like Cymbol or Unicode Map.

What characters are you trying to enter? Many special characters can be entered by touching and holding keys on the standard keyboard (or one of the many language keyboards).

Regarding new features: this is a user forum, no one here has knowledge of Apple's future plans.

You need to give some details about what it is you want to do, because ASCII Characters are what are already on the keyboard. It is non-ASCII that you might need to copy/paste.

I think you can be sure that Apple is never going to include a feature in iOS that has you input special characters by typing in numbers like Windows does it. Mac's have always used a different approach.

That's not possible (you can't add either keyboards or fonts to an iOS device yet), but there are some apps that let you make a custom keyboard that can be useful for some purposes: Unicode Map and UniKey.
