How to get the last character in variable

[4rczi]

I need to get the last character in variable.

For example, variable is:
45634T
I would like to get only the last character which is "T".
The characters are random, I don't know what will be in variable, I need to get the last character.

Hi,
You can use regex: (.{1})\s*$
