Convert JIS X 208 code to UTF-8 in Python

Question

Let's say I have this Kanji "亜" which is represented in JIS X 208 code in hex form: 0x3021. I want my Python program to convert that code into its UTF-8 form E4BA9C so that I can pass that string (URL-encoded) into my url like this

I'm using Python 2.7.12 but I'm open to Python 3 solution as well

Answer 1

These are accessed under ISO 2022 codec.

>>> '亜'.encode('iso2022_jp')
b'\x1b$B0!\x1b(B'

If I saw those bytes not framed by the escape sequence, I would have to know which version of JIS X 0208 is being used, but I'm entirely pattern matching on Wikipedia at this point anyway.

>>> b = b'\033$B' + bytes.fromhex('3021')
>>> c = b.decode('iso2022_jp')
>>> c
'亜'
>>> urllib.parse.quote(c)
'%E4%BA%9C'

(This is Python 3.)
