Converting Hex string to unicode

I am reading in a hex representation of Unicode characters as a string.(for example: 004100200042)

I want to convert the string from hex to unicode, and write the corresponding characters to a file. The output should look like follow:

A B(0041 = Capital A,0020 = space, 0042 = Capital B)

Could you please assist?
