5. Only uppercase. Letters **Ё** and **Ъ** are not available.
If the encoding does not support lowercase letters (e.g. `apple2`, `petjp`, `petscrjp`, `koi7n2`, `vectrex`),
then text and character literals containing lowercase letters are automatically converted to uppercase.
Only unaccented Latin and Cyrillic letters will be converted as such.
Accented Latin letters will not be converted and will fail to compile without `-flenient-encoding`.
To detect if your default encoding does not support lowercase letters, test `'A' == 'a'`.
