# How to create new custom symbols like \[Wolf]?

In Mathematica, we can often get very special symbols by typing esc ... esc or \[...], such as the Wolf or Mathematica's logo. Is it possible to define new special symbols like those and then use them as \[Wolf]?

Any Unicode character in the basic multilingual plane can be entered by typing \:xxxx, where xxxx is its code point in hexadecimal. You can of course define a more memorable input alias for it.
• @Itai May I ask you what encoding is used by the input form \xxx? For example, "\041" corresponds to the character "!" with code 33. Aug 27, 2017 at 3:37
