I'm aware of the ability to use accented characters by holding down a key until they appear (ie. á ü etc.); however, I'm curious as to how, if possible, one might enter a code point in hexadecimal format or otherwise to output the corresponding character?

This question came from our site for computer enthusiasts and power users.
There are applications in the App Store that display all of the characters allowed in the Unicode set that you can copy and paste into other applications like Mail and the like. Searching "unicode" in the App Store brings up a whole slew of them, both free and paid.
There is also Glyphboard (visit with your iOS device) that you can save as a bookmark on your iOS device for an easy interface to some of the more popular ones. This is very lightweight and changes every so often.

I have been looking for similar and the best third arty app I've found for arbitrary unicode inout is acalled UnicodeLab.
It allows you to input any unicode in decimal or hex, view it in multiple fonts, copy to clipboard. You can also cycle thorugh neighboring character codes easily.
It is free.
