@ -142,10 +142,11 @@ filled in with the formatted output.
This function is difficult to understand, and takes too many arguments.
This function uses a library-wide instance of **struct notcurses**, created
in **notcurses_init**. If **notcurses_init** is called multiple times in a
process's lifetime, behavior is undefined. If **notcurses_stop** is called,
behavior is undefined.
If UTF-8 is available, 'µ' (U+00B5 MICRO SIGN) will be used in place of
'u' (U+0075 LATIN SMALL LETTER U) for the 'micro-' prefix. This is
determined by **notcurses_init**/**ncdirect_init**. Once UTF-8 is detected,
it is used for the lifetime of the process. The alternative would require
accepting a **const struct notcurses** (and associated API break).
