Put again the (slightly edited) caution warning from Georg Baum about abusing the ucs4_to_qchar() conversion with symbol fonts. This comment was accidentally deleted in rev 18593.

// Caution: When using ucs4_to_qchar() in these methods, this is no

// why this works well for symbol fonts used in mathed too, even though
// these are not real ucs4 characters. These are codepoints in the
// modern fonts used, nothing unicode related.
// See comment in QLPainter::text() for more explanation.
