The Russian catalog's Isolate row began with a Latin "A" (U+0041),
"Aизолировать", and the Create New Sublayer and New Sublayer… rows
spelled "подслой" with a Latin "c" (U+0063). The rows now read
"Изолировать", "Создать новый подслой" and "Новый подслой…".
A new test fails when a word in any catalog's translation holds letters
from more than one of the Latin, Cyrillic and Greek scripts.
