I may be doing something wrong but see the difference at the end of the first line in the PDF (produced from CONTEXT) and the corresponding rendering in Chrome.

I observe this issue whenever there is a U+08F0 (or U+08F1 or U+08F2).  The two sides of this diacritic sign are not joined.

The other issue is with small gaps in between some letters and/or bad connection points.  See the second and third lines in the PDF.

Thanks,

MHB
