[Synology NAS] Fixed non-ASCII chars and more...(2020/09/11)

@LapinFou

First - i would to thank you. Your script seems to be exactly what i'm looking for. But i have two questions about it. Sorry but i found no answer in this thread.

• 1. I installed SABnzbd from GIT and not from a package. Did i have to change the first line and how?
  
  2. When i finally use your script - how do i setup the postprocessing scripts from Sickbeard, Couchpotato and Headphones?

Thanx in advance.
Efty

Hello!

First question, why not using the packages available here: http://www.synocommunity.com/? Synology Python package will NOT conflict with SynoCommunity one. Both can be installed at the same time. It is also much easier to install and update.

To answer your questions:
1- The 1st line of the script must be updated according to where your python is installed. It must be done with vi through a telnet session.
2- At the moment you must select my script OR the Sickbeard script when the d/l is started under SABnzbd. If necessary, I can have a look to see if it is possible to launch Sickbeard post-processing from my script. But it is not planned yet.

Not sure if it is the expected answers.... keep me in touch!

# If a file has been archieved under an ISO-8859 environment and unarchived
# under an UTF8 environment, then you will get an encoding format problem.
# The file will not be readable through SAMBA.
#
# Renaming script for SABnzbd runnning under Synology NAS.
# By default the NZB software is running under UTF-8 encoding format
# in order to correctly handle the french accents (éèàç...) a SABnzbd
# post-script must be run in order to convert the file encoding.
#
# To fix this problem, you must convert the encoding format
# to the UTF8 (default Synology encoding)
# The script is trying to detect if the original file/directory are coming
# from a RAR archive. In this case the unrar command on your Syno system will
# unpack in CP850 format (DOS).
# NB: in all cases, files will be readable through samba, even if the detection
# failed. But converted characters will not be good, ex: Î? instead é
#
# Remark: I guess it should work for any other encoding style. Just replace
# ISO-8859-15 (Western Europe) by the one coresponding to your country:

The tutorial has been updated. I added more explanations about how options are working.
If you got any troubles, please post a message!!

Today I've made a fresh install for SABnzbd and dowloaded some musicfiles. The script worked fine and after downloading and unpacking I saw the message: Character encoding translation done!

The only thing the script didn't change, were the files which contained the letter "ö", for example:

./0200 - Bl›f - Liefs Uit Londen.flac -> No special characters detected: Nothing to be done

The original name of the Artist is Blöf and al the files containing that specific character, weren't changed.

Other files worked like a charm, for example:

./0848 - André Hazes - 'n Vriend.flac -> CP437 detected: Renamed

Did I do something wrong here, or is the script unable to change the specific letter "ö"?

Your work is appreciated, hope you can help me out here, or do I have to change all those files still manually?

The problem is I can't move change or delete the files and still have to edit them via a TelNet session....

[LapinFou]

Hello StreameR,

First could you try again with the updated version (1.6) below?
I realized I've removed something which I should not, between version 1.4 and 1.5.
Maybe this is the root cause of your problem.


Then; if you still got the problem, could you contact me by PM in order to send me the NZB file which doesn't work well.

Thanks for the quick respond, and excuse me for being a noob.... I don't know how to update the script to the 1.6 version, is there some kind of tutorial available that guides me through this session?

[edit]
maybe I found the way to update the script, could you tell me if I am in the right direction?

I've downloaded notepad++, and copy/past the script (v1.6) above this post. After pasting the text into notepad++ I did this: Edit -> EOL Conversion -> Unix
After that I saved the file as CharTranslator.py

Now I have to copy that created file to the location /usr/local/sabnzbd/var/scripts and replace the "original" CharTranslator.py file?

If the above routing is correct, could you please confirm this to me? Now I have to find out how to copy the created file to the right dir on the DSM.....
[/edit]

[LapinFou]

You are complety right. Now if you copy the file in your video share folder from windows, your file should be visible in:
/volume1/video/CharTranslator.py
Then from a telnet session use the command:
cp -rf /volume1/video/CharTranslator.py /usr/local/sabnzbd/var/scripts/

[StreameR]

Okay, thanks for the info!

Someone at the Dutch Synology forum also helped me, and recommended me to use the package Config File Editor by MertyMade. This worked for me, and atm I am downloading the files again to see if the problem is solved in Version 1.6

I will let you know what the results are, thanks a lot so far!

[UPDATE]

Strange, when I take THIS file everything seems to work fine and I get the following message:

When I download THIS file (a part of a bigger collection songs) than the script doesn't change it..

./0155 - Bl›f - Aan De Kust.flac -> No special characters detected: Nothing to be done

I'm using v 1.6 of the script and I'm curious what causes this, and if I have to change the files manually?

[/UPDATE]

[LapinFou]

Could you contact me by PM? I need the NZB file which is failing in order to do some testing at home and to fix the problem.
Unfortunately, so far, you must fix the file through a telnet session or wait for the version 1.7 which will surely fix the problem!!

[LapinFou]

OK.
Version 1.7 is out.
The problem below is coming from the usage of Scandinavian code page + a hole in my detection function.
The hole was punched. But unfortunately, I can not detect the difference between code 437 and 865 (Danish, Norwegian).
So, with the fix below, the character will be badly renamed. However, this time, the file will be accessible from Windows/File Station.
I hope Scandinavian people can leave with this restriction.


Depending of where your NZB source is coming from, you may replace the .decode('cp437') Python code, with the one matching your country: Python Standard Encodings

[LapinFou]

I hope I'm done for today!!

I'm waiting StreameR feedback.

The version 1.8 is out.
In fact the problem was, I should use cp850 decoding style instead cp437.

lol, me too! Good to see the problem is solved, and glad that I could help you out there!

Keep up the good work m8!

Latest version of CharTanslator script is now included into the latest SABnzbd (SynoCommunity version for Synology NAS).

[LapinFou]

Code: Select all

#!/usr/local/python/bin/python -OO
#-*- coding: iso-8859-15 -*-
#
# If a file has been archieved under an ISO-8859 environment and unarchived
# under an UTF8 environment, then you will get an encoding format problem.
# The file will not be readable through SAMBA.
#
# Renaming script for SABnzbd runnning under Synology NAS.
# By default the NZB software is running under UTF-8 encoding format
# in order to correctly handle the french accents (éèàç...) a SABnzbd
# post-script must be run in order to convert the file encoding.
#
# To fix this problem, you must convert the encoding format
# to the UTF8 (default Synology encoding)
# The script is trying to detect if the original file/directory are coming
# from a RAR archive. In this case the unrar command on your Syno system will
# unpack in CP850 format (DOS).
# NB: in all cases, files will be readable through samba, even if the detection
# failed. But converted characters will not be good, ex: Î? instead é
#
# Remark: I guess it should work for any other encoding style. Just replace
# ISO-8859-15 (Western Europe) by the one coresponding to your country:
