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'`.
