*** Strip off UTF-8 BOM
IF STARTSWITH(lcRetVal,"??)
  lcRetVal = STRCONV(SUBSTR(lcRetVal,4),11)
ENDIF

Something (or somebody..) must have changed a " into a ?. This is an excerpt from wwutils.prg, compare it to your own copy, and correct it if necessary:

   *** Strip off UTF-8 BOM
   IF STARTSWITH(lcRetVal,"?")
	 lcRetVal = STRCONV(SUBSTR(lcRetVal,4),11)
   ENDIF

This is due to the language I suppose. The characters of the string are not readable in Korean (?)?

The code should look like this:

IF STARTSWITH(lcRetVal,"")
   lcRetVal = STRCONV(SUBSTR(lcRetVal,4),11)
ENDIF

What's happening is that in Korean code page those characters are not part of the ASCII upper set so the characters are not valid - hence ??.

You might try this:

*** Strip off UTF-8 BOM
IF STARTSWITH(lcRetVal,CHR(239) + CHR(187) + CHR(191))  
   lcRetVal = STRCONV(SUBSTR(lcRetVal,4),11)
ENDIF

Fixed this in wwutils.prg.
