Noto Sans SC, missing glyphs, glyphs too wide #84

Using this Noto Sans SC OTF font with the PHP library dompdf, I see some missing glyphs. Eg, "订单" is rendered as: The expected rendering is: I'm afraid I can't tell if the problem is php-font-lib, dompdf, or the PDF viewer.

I also see very wide spacing for numbers and Latin glyphs: Maybe this is a problem with the metrics from php-font-lib? It makes the font unusable, as the text may be Chinese or Latin and spacing like this makes the Latin much too wide.

After further research it seems there were a lot more problems than just the above and the cause is that OTF is not supported. Using TTF solved all the problems.
