I tried to destring a variable but the "destring" return strange message.
When I looked at the characters contain in the variable, i get the below.
Any help would be appreciated.

. charlist s_p_500__includes_dividends_0
.0123456789��


destring s_p_500__includes_dividends_0, generate(sp) ignore(`"��"', illegal) force
baa_corporate_bond invalid name
