Hi, it's not hard to implement everything you want using IDirectFBFont::GetStringWidth() and then draw one line at a time. Justification can be done using DSTF_TOPLEFT et al. Why do you think you can't implement this on top of DirectFB? For more advanced text rendering you should consider using pango. You should also remember that the length in bytes may legally be != length in characters, since this is UTF-8 encoded text.
