Pointer<SdlIconvT> sdlIconvOpen(String? tocode, String? fromcode)

This function allocates a context for the specified character set conversion.

\param tocode The target character encoding, must not be NULL. \param fromcode The source character encoding, must not be NULL. \returns a handle that must be freed with SDL_iconv_close, or SDL_ICONV_ERROR on failure.

\since This function is available since SDL 3.2.0.
