split string with hieroglyphs

[Belize]

Hi.
Essence of problem in the following:
Here is lines in utf8 of this form "BZ?ツーリTV%ツキDVD"
Is it possible to split them into the fragments that contain only latin
printable symbols (aplhabet + "?#" etc)
and fragments with the hieroglyphs, so it could be like this
['BZ?', '\xe3\x83\x84\xe3\x83\xbc\xe3\x83\xaa', 'TV%',
'\xe3\x83\x84\xe3\x82\xad', 'DVD'] ?
Then, after translate of hieroglyphs, necessary to join line, so it
could be like this 
"BZ? navigation TV% display DVD"
Thanks.
