But my music files are located on a “Lacie Networkspace Drive” which is Linux based.
The NAS operating system is irrelevant. XP sees it as a network drive.
Is the problem with the non ASCII characters fixable within the database or is the problem in fact in Firefly?
Firefly sometimes chokes & crashes when it encounters on non-ASCII characters during the database build / update process. The db is left corrupted and incomplete when this occurs.
