Hello,
I love the helper functions from SysUtils' `TStringHelper`. Unfortunately,
they're only available for `String`, but not for other types like `Utf8String`
or `RawByteString`.
Is it safe to cast to `String()` and then invoking the helper, e.g.
`String(AUtf8String).IndexOf('foo')`? Or does this casting involve a codepage
conversion?
I've tried with my FPC installation:
program Project1;
uses sysutils;
var S: Utf8string;
begin
S := 'äfoo';
writeln (String(S).IndexOf('f')); // prints "2", as expected
end.
But can I rely on it?
Are there any plans of making string helpers available for `Utf8String` and
`RawByteString`?
Kind regards,
Thomas
