Alan - not sure whether this still is an issue or not. But I think you've been working on this?

With 7.6 this is working fine for the SP UI (Touch, Radio, Controller). I can set the Library name to "Džuboks" and the Various Artists label to "Συλλογές" and all seems to work as expected.

The library name is corrupted in the ip3k-Player-UI and the Web-UI player-selector drop-down.

With the Greek VA label above, the ip3k-Player-UI display gets corrupted when browsing within Artists/VA. A couple of Greek character seem to be left as ghosts on line-2. Andy, do you have any idea?

Actually, the library name is fine in the Web-UI if both servers are 7.6.

For ip3k players, the available character-set for library name is restricted to ISO-8859-1.

I have confirmed that the ip3k player display corruption occurs with Boom f/w 54, and is therefore not related to the recent scrolling-display changes, unless the issues are server-side.

To recreate, browse: My Music / Artists / Συλλογές
There are several issues:
1. the all-caps version of "Συλλογές" in line-1 of the display is wrong when in that display-mode (standard).
2. the album name in line-2 is corrupted (overlayed) with some other glyphs in display-mode standard.
3. The artist name ("Συλλογές"), which should be on line-1 in 2-line mode, is instead superimposed on the album name in line-2.

Triode, are you able to shed any light on this issue?

I have spun off bug 16812 to handle this issue with display corruption.

The original issue of this bug, with regard to the Various Artists name and the library name, are fixed in 7.6.

For ip3k players, library names are still restricted to the 8859-1 character set in the firmware setup menus when selecting a server to connect to.

Ip3K   see's ??????? for library name selection as noted by Alan in comment #12
