#
-# Modified by Paul Hardy, June 2008.
+# - Updated comments to use Luis' full name and add a link to
+# the Unifont page on savannah.gnu.org.
+# - Store combining character code points for the entire Unicode
+# range, not just for the Basic Multilingual Plane.
+# - Change "Encoding: UnicodeBmp" by detecting whether the highest
+# glyph is in the Basic Multilingual Plane or above that; if above,
+# use "Encoding: Unicode" instead.
+# - Add explicit definitions for three TrueType code points:
+# ".notdef", ".null", and "nonmarkingreturn". These override
+# the defaults that Fontforge creates. The ".notdef" and
+# "nonmarkingreturn" glyphs now have widths of 8 pixels
+# (512 units in the SFD output file).
+# - Calculate exact number of glyphs in the font for "BeginChars" entry.
+# - Convert the pixel outline drawing portion of this script
+# to a subroutine.
+# - Add "uni" prefix to StartChar description of Unicode code points.
#
-# The original code above didn't work properly. The replacement code
-# below wastes RAM, but it works as a quick fix.
+#
+# Read the list of combining characters, which will have zero width.
