Delphi’s NextGen compilers (Android, IOS) removed support for UTF8String, AnsiString and RawByteString. But if you look into System.pas you see that those types are still there but Embarcadero makes them inaccessible from outside of System.pas by prefixing them with an underscore that the compiler converts to the at-sign. And you can’t write “@UTF8String” as it is not a valid identifier.
By patching DCU files it is possible to make those hidden types accessible. And guess what, the compiler generates correct code for the “unsupported” strings.
The unit System.ByteStrings reintroduces:
  • ShortString
  • AnsiString
  • AnsiChar
  • PAnsiChar
  • PPAnsiChar
  • UTF8String
  • PUTF8String
  • RawByteString
  • PRawByteString

Usage:
Add the System.ByteStrings.dcu’s path to the compiler’s search path and add the unit to your uses clauses.

There is no *.PAS file because the DCU is patched with a hex editor to get access to the hidden types.
