From what I've seen in the wild in Japan, Roman/ASCII characters are
widely used for object/attribute names, as generally it's much less
hassle than switching between input methods, dealing with different
encodings etc. The only place where I've seen Japanese characters widely
used is in tutorials, examples etc. However that's only my personal
observation for one particular non-Roman language.
