Problems in artist editing

first example:

i edited the artist in order to “romanize” the greek alphabet name.
but in the edit windor i still see the original one.
on the other hand, if i make a search with the original name i get nothing

this is not very desiderable (the search usually returns also non immediate results, for example surnames or a.k.a.'s …)

there is also another problem, concerning cyrillic alphabet.
here an example:

if i edit the artist to use latin letters, i get:

note that in this case the cyrillic name is lost…
