TCPSend( ) only transmits half simplified Chinese characters

[txj]

In AutoIt 3.3.6.0, run example in TCPRecv( ) first, then run example in TCPSend( ).

now, input some simplified Chinese characters in "Data for Server" dialog box, only half simplified Chinese characters diaplayed in "My Server" dialog box. see picture.

TCPSend( ) only sends half simplified Chinese characters

[J-Paul Mesnage]

In fact TCPSend/TCPRecv work with ANSI or binary. Not sure what can be done to have UNICODE chars going thru...

The following works. From the examples you mention, change the client line 48 into
TCPSend($ConnectedSocket, StringToBinary($szData, 4))
and in the server, change lines 67+:
{{{ ; Try to receive (up to) 2048 bytes

;----------------------------------------------------------------
$recv = TCPRecv($ConnectedSocket, 2048, 1)

; If the receive failed with @error then the socket has disconnected
;----------------------------------------------------------------
If @error Then ExitLoop

; convert from UTF-8 to AutoIt native UTF-16
$recv = BinaryToString($recv, 4)

; Update the edit control with what we have received

}}}

This way, you transmit UTF-8 data. If the client has to send both binary and string data, you need to make the server aware of that so that it doesn't "decode from UTF-8" actual binary data that would instead need be passed verbatim.

Thanks jchd,
I will add some doc info about this situation.

I change code as you mention above, all simplified Chinese characters send OK.

thank you, jchd.
