How to convert QString to ASCII ?

[sonichy]

I need something like this:
if ( "a" == "b" -1 ) ......
ASCII:
if ( 97 == 98 - 1 ) ......

@sonichy
see QChar::toLatin1() which returns a char which also can be cast to an int
to get the QChar, use QString::at()

Use single quotes instead of double quotes: if ( 'a' == 'b' -1 ) this is pure C++, nothing Qt specific

cast to an int

QString a = ...;
QString b = ...;
ushort as = a.at(0).unicode();
ushort bs = b.at(0).unicode();
qDebug() << a << as << b << bs;
if(as != bs-1) return false;

QByteArray a_ascii = a.toLatin1();
