Question About Print Output

[manyoyo-co]

Hello, I'm wondering why there are single quotes used around the filename after 'Adding metadata' but double quotes after 'Adding thumbnail'.

Sorry to ask again, but I'm really interested.

[ffmpeg] Adding metadata to 'Leonard Nimoy reads Ray Bradbury's 'There Will Come Soft Rains' from 'The Martian Chronicles'-LzhlU8rXgHc.mp3'
[ffmpeg] Adding thumbnail to "Leonard Nimoy reads Ray Bradbury's 'There Will Come Soft Rains' from 'The Martian Chronicles'-LzhlU8rXgHc.mp3"

Thank you in advance.

Are you trolling or what?

No, I'm not -- really. :-/

I'm genuinely, 100% interested in the difference between the print output in these two lines. I'm sure there might be a completely logical reason for it, but I don't know what it is. Sorry.

I'll repeat it 3rd time: there is no logical reason. First uses single quotes hardcoded in string literal, second uses double quotes.
