[xsd-users] Regarding bugs - Type Mismatch: Signed to Unsigned

[Muralidhara B K]

Hi Boris,

These issues are reported with high severity in our static analysis tool ,it will be great if   you provide fix or add explicit casts.


Thanks & Regards,

Firstly, there is no function return on these lines. Rather, it's an assignment of char to unsigned char as part of the UTF8 sequence analysis. These are not bugs but we can add explicit casts if that helps.
