Setting the Unicode text of a field from JSON converted to array

Sun, 09 Nov 2014 20:08:12 -0800

in LC 6.6.2, Mac OS X Maveriks, calling data from MySQL dBase on our web server into a desktop thin client.
I have a field that is being set to unicode... the default font is Lucida Grande, which supports Tamil. 


I'm on a mac: if I paste Inaimathi (Tamil Unicode font) into the field, 
the Tamil script appears as expected, if I go to PHPMy Admin log into 
our webserver and look at a field with lyrics and copy and paste into my 
livecodes stack (or email or pages) it all works... I get Tamil script




but if I fetch that same field as JSON... I get raw unicode from our web 
serve (the use case is lyrics for songs)


and put it into var tJSON

I get something like this which I can push to the message box:

put tJSON

"song_title":"Anbar Anbathu",

so far so good...Now bhow to get strings like:


\u0b9a\u0bbf\u0bb5\u0b9a\u0bbf\u0bb5\u0b9a\u0bbf\u0bb5\r\n\r\n\u0bae\u0bc1\u0ba9\u0bcd\u0baa\u0bbf\u0ba9\u0bcd 
\u0b85\u0bb1\u0bcd\u0bb1\u0ba4\u0bc1



to appear as Tamil in the same liveCode field where I can paste it...and 
get proper script?



Now.. I have included libJSON (Mark Smith) in my stack and if I take the 
above


and do this:

put jsonToArray(tJSON, true) into tLyricsA
put tLyricsA[1] into sLyricsA


# OK now the among the keys are one "original_script", which as you can 
see above is coming in as raw unicode...

# but

put sLyricsA["original_script"] into tContent
put tContent

things get strange:

I get this in the msg box

…©Íª°©Íª€Á



…©Íª°©Íª€Á ¿µ¿µ¿µ

†ȯ±Í±€Á ¿µ¿µ¿µ

‡©Íª®¯®€Á ¿µ¿µ¿µ

ˆ©Á¯¿°Í€Ê±ÁˇÍ ¿µ¿µ¿µ

[snip, more garbage)

and if I do:

set the text of field "lyrics" to unidecode(tContent, "utf8")

we get this in the field:

ÍßâÎؙͶ°ÎØ™Óüõ‡¥†‡¥äϧäÓ™©Íܪә©Ìƪ‚ÉßÏÄÇ µÎóÄÏÄLJ∂µÍÄäÓ§ÇÎá∏Îá™Ó

So... to test and remove the JSONtoARRay function out of the equation...


I made this little button, then copy the unicode 
"\u0b9a\u0bbf\u0bb5\u0b9a\u0bbf\u0bb5\u0b9a\u0bbf\u0bb5\r\n\r\n\u0bae\u0bc1\u0ba9\u0bcd\u0baa\u0bbf\u0ba9\u0bcd 
\u0b8 etc" to my clipboard


on mouseUp
put the clipboardData["text"] into tContent

set the unicodetext of fld "lyrics" to unidecode((tContent,"utf8") 
#outputs garbage:


郧莽釧ꖹ뇢ꊔ駦뢈



set the unicodetext of fld "lyrics" to uniencode(tContent,"utf8") # 
returns the clipboard untouched:


"\u0b85\u0ba9\u0bcd\u0baa\u0bb0\u0ba9\u0bcd\u0baa\u0ba4\u0bc1...etc"

What am I doing wrong?
