Concerning band's name.
First, you might want to check edits 9955851, 7608457 and 8253743.
Second, the key is the band's name forming story, provided by greycat:
"The story's with the name is really simple: Flëur, being an Ukrainian band, failed to find a decent label to subscribe them in their homeland, but were well-received in France, at Prikosnovénie label. But several other bands named "Fleur" already existed, so label management advised them to add diacritic in their label to make it unique".
As you can see, the band's name was primary fully in Latin, with Latin "e", to which a diaeresis was added (this also excludes the use of Cyrillic "ё" as ArtistIntent).
The name Flëur does not use Cyrillic "ё", it uses Latin encoded diaeresis.
