This shows the problem:
void RenderCharPath2(const char* gbuf, unsigned total_size, FontGlyphConsumer& sw, double xx, double yy)
{
	const char* cur_glyph = gbuf;
	const char* end_glyph = gbuf + total_size;
	Pointf pp(xx, yy);
	while(cur_glyph < end_glyph) {
		const TTPOLYGONHEADER* th = (TTPOLYGONHEADER*)cur_glyph;
		const char* end_poly = cur_glyph + th->cb;
		const char* cur_poly = cur_glyph + sizeof(TTPOLYGONHEADER);
		sw.Move(fx_to_dbl(pp, th->pfxStart));
/*		while(cur_poly < end_poly) {
			const TTPOLYCURVE* pc = (const TTPOLYCURVE*)cur_poly;
			if (pc->wType == TT_PRIM_LINE)
				for(int i = 0; i < pc->cpfx; i++)
					sw.Line(fx_to_dbl(pp, pc->apfx[i]));
			if (pc->wType == TT_PRIM_QSPLINE)
				for(int u = 0; u < pc->cpfx - 1; u++) {
					Pointf b = fx_to_dbl(pp, pc->apfx[u]);
					Pointf c = fx_to_dbl(pp, pc->apfx[u + 1]);
					if (u < pc->cpfx - 2)
						c = Mid(b, c);
					sw.Quadratic(b, c);
				}
			cur_poly += sizeof(WORD) * 2 + sizeof(POINTFX) * pc->cpfx;
		}
*/		sw.Close();
		cur_glyph += th->cb;
    }
}


This renders OK:

void RenderCharPath2(const char* gbuf, unsigned total_size, FontGlyphConsumer& sw, double xx, double yy)
{
	const char* cur_glyph = gbuf;
	const char* end_glyph = gbuf + total_size;
	Pointf pp(xx, yy);
	while(cur_glyph < end_glyph) {
		const TTPOLYGONHEADER* th = (TTPOLYGONHEADER*)cur_glyph;
		const char* end_poly = cur_glyph + th->cb;
		const char* cur_poly = cur_glyph + sizeof(TTPOLYGONHEADER);
		sw.Move(fx_to_dbl(pp, th->pfxStart));
		while(cur_poly < end_poly) {
			const TTPOLYCURVE* pc = (const TTPOLYCURVE*)cur_poly;
/*			if (pc->wType == TT_PRIM_LINE)
				for(int i = 0; i < pc->cpfx; i++)
					sw.Line(fx_to_dbl(pp, pc->apfx[i]));
			if (pc->wType == TT_PRIM_QSPLINE)
				for(int u = 0; u < pc->cpfx - 1; u++) {
					Pointf b = fx_to_dbl(pp, pc->apfx[u]);
					Pointf c = fx_to_dbl(pp, pc->apfx[u + 1]);
					if (u < pc->cpfx - 2)
						c = Mid(b, c);
					sw.Quadratic(b, c);
				}
*/			cur_poly += sizeof(WORD) * 2 + sizeof(POINTFX) * pc->cpfx;
		}
		sw.Close();
		cur_glyph += th->cb;
    }
}


I will now check the next suggestion with raw pick.

BR, Tom
