How to make unicode characters?

I understand that \u can help make unicode characters like "\u00E4" becomes "ä".
How can I take a variable like "00E4" and convert it to "ä"? I cannot do "\u#{var}". I ithink first convert from hex to integer maybe?

iex(1)> a = 0x00E4 
228
iex(2)> to_string([a])
"ä"

I hope this could help.

Edit:

iex(1)> a = "00E4"
iex(2)> int = String.to_integer(a, 16) 
228
iex(3)> to_string([int])
"ä"
