Insert Unicode Symbol

Hi,
i am searching a way to insert in a description or in a generic field few characters that belong to Unicode, for example

  • U+12000–U+123FF Cuneiform

Somebody has already had this kind of problem?

We don’t provide any special facilities for choosing Unicode characters, but you can use your operating system’s methods for doing so: usually there’s some character map option as well as some kind of key combination where you input the codepoint.
