Unicode -> ASCII

mpullin

Anyone written a Unicode to ASCII function? I'm thinking of writing one myself, because I need to store something a module sends my touchpanel in a variable, but it's being sent to the touchpanel in a ^UNI- command. e.g.

Line      3 :: Command To [33033:1:1]-[^UNI-116,0,005200450050004500410054007C0041004C004C] - 11:54:16

Basically I am going to read 4 characters at a time and use hextoi followed by type_cast to get a character, and add it to my string. But there is probably a better way.

If you do a search for ?Unicode? in Netlinx keywords help there are a bunch of Unicode functions that are available such as:

_WC
CH_TO_WC
WC_COMPARE_STRING
WC_CONCAT_STRING
WC_DECODE
WC_ENCODE
WC_FILE_CLOSE
WC_FILE_OPEN
WC_FILE_READ
WC_FILE_READ_LINE
WC_FILE_WRITE
WC_FILE_WRITE_LINE
WC_FIND_STRING
WC_GET_BUFFER_CHAR
WC_GET_BUFFER_STRING
WC_LEFT_STRING
WC_LENGTH_STRING
WC_LOWER_STRING
WC_MAX_LENGTH_STRING
WC_MID_STRING
WC_REMOVE_STRING
WC_RIGHT_STRING
WC_SET_LENGTH_STRING
WC_TO_CH
WC_TP_ENCODE
WC_UPPER_STRING

Maybe one of the above may be of some help?

Also can't find WC_TO_CH. My compiler is v.2.4.0.1. I'll see if I can do it after I do a WebUpdate and get the latest NS.

Oh... you have to #INCLUDE 'UnicodeLib.axi'


This code just gets me a bunch of question marks... I'm starting to get frustrated with this Unicode thing

DEFINE_FUNCTION CHAR UNI2ASCII (CHAR c[]){
    return TYPE_CAST(WC_TO_CH(_WC(c)))
}

There is a checkbox under the ?Netlinx Compiler? tab under Preferences that says ?Enable_WC Preprocessor (Unicode)? that needs to be checked if you want to use the library, or so I assume. I've never used any of the functions myself.

Finally solved it this morning. This function does the trick:

DEFINE_FUNCTION CHAR[1] UNI2ASCII (CHAR c[]){
    // passed '0042' will return 'B'
    STACK_VAR INTEGER yy
    yy = hextoi(RIGHT_STRING(c,2))
    RETURN "yy"
}
