Can't play specific songs (probably Unicode related)

[trbjo]

I have a problem playing a specific song. The bug only exists in your workflow since I don't have any problems playing it in https://github.com/valrus/alfred-mpd. I can send you the song if you want to test it yourself.

I have a problem playing a specific song

I can't possibly help unless you tell me which one…

[trbjo]

It concerns all songs that contain special characters i.e. the Danish letters æøå. I can play it from another Alfred-workflow (the https://github.com/valrus/alfred-mpd), so it's not the songs that are corrupted or anything like that. It has no problems showing the characters it just refuses to play the song with the message "error adding: thesonginquestion.mp3: No such directory"
Do you want me to send it to you?

[trbjo]

I have the same problems with the Ulysses-alfred workflow. I can hardly read python, but it appears to me that he has used your python library to create his workflow. Could it be that there is a bug somewhere in it?

I'll test it if I come across other workflows that rely on your library.

[deanishe]

Do you want me to send it to you?

No, thanks. Just the title/file name that contains non-ASCII characters, please.

Also the error message from Alfred's debugger.

Could it be that there is a bug somewhere in it?

It's very well tested with non-ASCII and is used by hundreds of workflows.

The problem is with the workflows themselves. Handling non-ASCII in Python 2 is a notorious source of errors.

[trbjo]

It could be "15 Skøn Er Våren.m4a", but it's basically related to all songs with æ, ø and å.

[deanishe]

Thanks. That was what I needed to identify the issue. Should be fixed in v0.1.3.

Best guess is that it's because mpc isn't a native macOS program. Native APIs transparently normalise paths to the correct form for the FS. I've changed the default normalisation form in the workflow to match the FS.
