    Use correct UTF8 length when converting JSStrings
    
    JSStringGetLength returns the number of UTF8 chars in the string, using this
    value results in trimmed strings when they contain UTF8 chars.
    The correct function is JSStringGetMaximumUTF8CStringSize that reports the
    number of bytes the string requires to be allocated, including null-byte.
    
    Bug #609936
