For readability, the table is slightly

The argument is a string which specifies which language you are using;
that affects the choice of transliterations slightly.
Possible values are listed in `cyrillic-language-alist'.
If the argument is t, we use the default cyrillic transliteration.
If the argument is nil, we return the display table to its standard state."
