@Sayse Not quite. There's a gigantic difference between a string like `'0xb3d9'` and a string like `'\xfd'`. — Aran-Fey, Oct 12 '18 at 10:21

This character is multibyte. I think this problem is different from the content of the link. — M2KS, Oct 12 '18 at 10:30

First, obtain the integer value from the string of a, noting that a is expressed in hexadecimal:

a_int = int(a, 16)

Next, convert this int to a character. In python 2 you need to use the unichr method to do this, because the chr method can only deal with ASCII characters:

a_chr = unichr(a_int)

Whereas in python 3 you can just use the chr method for any character:

a_chr = chr(a_int)

So, in python 3, the full command is:

a_chr = chr(int(a, 16))

The problem is 'ValueError: chr() arg not in range(256)'. This character is multibyte. I do not know how to convert multibyte to character. – M2KS Oct 12 '18 at 10:28
That means you are using python 2. So use `a_chr = unichr(int(a, 16))` – Rob Bricheno Oct 12 '18 at 10:30
