UTF-8 question - 2.87

[Kevin Lynch]

Thanks everyone for the tremendous work in keeping my favourite s/w
package up to date.

I've not upgraded yet but I've seen the warnings about using UTF-8 characters.
I just want to be clear about what will cause trouble and what will be safe. I

I'm a fan of traditional Irish folk music and so one of the shows I
download is this thing
Cúlán - http://www.bbc.co.uk/programmes/b04l3xbn
I've noticed
 - The diacritical characters get mashed in file names (does not cause
me an issue)
 - my music player renders the mashed characters correctly as they are
stored in the mp3 metadata.
 - problems using the command line to add the pvr search; used the web
ui found the show there and added it to my pvr searches

Is this what is expected or are their more serious problems imminent

Thanks

Kevin
