Just to remind, the {{fname|rfm.send()}} only accepts binary data as generated with bytes() or bytearray(). The message string must be converted to a binary with {{fname|bytes()}}. As binary data does not accept value > 127 without a proper encoding then the bytes() conversion must identifies the encoding of the source string to applies the adequate encoding scheme (UTF8 -> Binary).
