WM_GETTEXTLENGTH change in winproc.c

I don't understand it :

    719     case CB_GETLBTEXTLEN:
    720     case LB_GETTEXTLEN:
    721         /* there may be one DBCS char for each Unicode char */
    722         return result * 2;

This has a bad effect on one of my test apps - returns a length of 12
for a text of 6 characters, displays funny symbols after the text.

The Unicode window proc returns 6, why the unicode/ascii conversion
should make it 12 ? The Api returns number of chars, not bytes.
