string.uchar is a function that is part of the Extended Standard Library.

Unicode characters may be included in strings by encoding them in UTF-8. This routine converts one or more Unicode character numbers into a UTF-8 string.

This has been introduced in TI-Nspire OS 3.0 (Changes).

a_tilde = string.uchar(227) -- ã
a_diaer = string.uchar(228)
a_ring  = string.uchar(229)
e_acute = string.uchar(233) -- é
e_grave = string.uchar(232) -- è
o_acute = string.uchar(243)
