Description

As of version 10.5.4, we use the uint data type to store flags like MY_REPERTOIRE_ASCII, MY_REPERTOIRE_EXTENDED, etc.

For stricter data type control, let's add a separate enum-based data type as follows:

typedef enum enum_repertoire_t

  MY_REPERTOIRE_NONE=        0,

  MY_REPERTOIRE_ASCII=       1, /* Pure ASCII            U+0000..U+007F */

  MY_REPERTOIRE_EXTENDED=    2, /* Extended characters:  U+0080..U+FFFF */

  MY_REPERTOIRE_UNICODE30=   3  /* ASCII | EXTENDED:     U+0000..U+FFFF */

} my_repertoire_t;

and fix the related classes and routines to use the new data type.
