Wanted: idiot's guide to using Unicode in Rev

[Kenji Kojima]

Ben,

Convert the whole field ascii to unicode.
Maybe this is the one of workarounds.
AsciiToUni was made by Kiyoshi Kamogawa.

on asciiToUni pFldName, pLang
   if pLang is "" then
     put ",japanese" into pLang
   end if
   put number of lines of fld pFldName into tNumOfLines
   lock screen
   repeat with i=1 to tNumOfLines
     put 0 into tNumOfChars
     repeat with h=1 to (number of chars of line i of fld pFldName)
       if (textFont of char h of line i of fld pFldName) contains "," 
then
         put tNumOfChars + 2 into tNumOfChars
         put h + 1 into h
       else
         put tNumOfChars + 2 into tNumOfChars
       end if
     end repeat
     repeat with j=1 to tNumOfChars
       if (textFont of char j of line i of fld pFldName) contains "," 
then
         put j + 1 into j
       else
         set useUnicode to true
         put uniEncode(char j of line i of fld pFldName) into tUniChar
         put tUniChar into char j of line i of fld pFldName
         set textFont of char j to j+1 of line i of fld pFldName to pLang
         set useUnicode to false
         put j+1 into j
       end if
     end repeat
   end repeat
end asciiToUni
