Encode to UTF-8 and then decode to TP.

MorgoZ

Hello,

My app takes some user data from a TP keyboard.
I need to store that data in UTF-8 format, and then, show the UTF-8 formatted data on the TP again.

What i'm trying so far is:

1.- Encode the data received from the keyboard to UTF-8.

wcAux = wc_decode(acDataText,WC_FORMAT_TP,1)
scStudyCase.Patient.Name = wc_encode(wcAux,WC_FORMAT_UTF8,1)

2.- Take the encoded data and show it on the TP:

wcAux = wc_decode(acAux,WC_FORMAT_UTF8,1)
                acAux = wc_tp_encode(wcAux)                
                send_command dvTp, "'^UNI-',itoa(anAddressItemData[nAux][4]),',0,',acAux"

But, the text at the TP is in blank.

I've also tried other ways to implement similar tests using _WC and wc_to_char or char_to_wc, but none worked for me.

Thanks for your help!!

Are you sure the font you're using on the TP has those chars? Not a good suggestion, but worth a try.

Here's the function I use for sending utf-8 text, maybe you can find something useful in it. Also make sure you have "Enable _WC Preprocessor (Unicode) checkec in NS Preferences > Netlinx Compiler and make sure you have #INCLUDE 'UnicodeLib.axi' in your module and main.

Thanks for your responses,

finally, the solution was that i was receiving data from the TP input fields in ASCII format, so i just had to decode the ASCII data and encode it in UTF-8.

The code:

                    wcAux = wc_decode(texto,WC_FORMAT_ASCII,1)
                    acAux = wc_encode(wcAux,WC_FORMAT_UTF8,1)
                    scStudyCaseSearch.Patient.FamilyName = acAux

Then, with the data in UTF-8, i can properly store latin characters and use them in a server-PC's database.

Salutes!
