I'm writing a script in python to generate thumbnail for my NEF files (Nikon raw).

So far so good. I have the .png image in 256X256, 8bit, non-interlaced PNG image with full alpha transparency as requested by this doc: https://specifications.freedesktop.org

Then we generate the md5 hash of the URI:

from urllib.parse import quote
import hashlib

path = 'file:///home/ricardo/Área de Trabalho/TempImgX/teste.png'
print(path)

print('-----------------------------------------------')

# Deal with special character
temp1 = (quote(path, safe=''))
print(temp1)

print('-----------------------------------------------')

# md5 of URI
temp2 = hashlib.md5((temp1).encode()).hexdigest()
print(temp2)

Output:

file:///home/ricardo/Área de Trabalho/TempImgX/teste.png
-----------------------------------------------
file%3A%2F%2F%2Fhome%2Fricardo%2F%C3%81rea%20de%20Trabalho%2FTempImgX%2Fteste.png
-----------------------------------------------
d0d4c55153f15c3b55a355ad75362f90

Process finished with exit code 0

Now if I move my thumbnail to .../thumbnails/large with the name: d0d4c55153f15c3b55a355ad75362f90.png

It should work right? But it does not!

Even if I don't treat the special characters with (quote(path, safe='')) it would still not work.

None of the examples I found on the web use special characters, maybe I'm doing it wrong...

Any thoughts?
