I am using pyserial and need to send some values less than 255. If I send the int itself the the ascii value of the int gets sent. So now I am converting the int into a unicode value and sending it through the serial port. 

unichr(numlessthan255);

However it throws this error:
'ascii' codec can't encode character u'\x9a' in position 24: ordinal not in range(128)

Whats the best way to convert an int to unicode?

In Python 2 - Turn it into a string first, then into unicode.

str(integer).decode("utf-8")

Best way I think. Works with any integer, plus still works if you put a string in as the input.

Updated edit due to a comment: For Python 2 and 3 - This works on both but a bit messy:

str(integer).encode("utf-8").decode("utf-8")
