Thumbnail md5 hash special characters

0

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?
