+# Corrected version of user-submitted code in https://github.com/rougier/freetype-py/issues/193
+
+# Comments:
+#     The original version missed "freetype.FT_LOAD_RENDER" and
+#     "freetype.FT_LOAD_TARGET_MONO", and also has the unfortunate
+#     setting of pixel size "16". Thus for some glyphs on 'simsun.ttc',
+#     the code returns the embedded bitmap, while for other glyphs without
+#     embedded bitmaps, it returns garbage for the bitmap buffer
+#     (if you do not check "font.glyph.format" and "font.glyph.bitmap.pixel_mode" ;
+#     font.glyph.format == FT_GLYPH_FORMAT_OUTLINE in that case). "bitmap.pitch" was also
+#     not used in the original, and hard-coded length of scanline was used.
