+    BitPattern.woff is a font with a glyph for each mirrored character.
+    (The glyph is a bit pattern of the character's code point, hence the
+    font name.)  The font was generated by:
+    
+      1. Creating an input file that consisted of a four-hex-digit code
+         point per line, for each glyph to be included in the font.
+         (For this test, that would be the 360-odd mirrored characters.)
+
+      2. Running ./generate-bitpattern-font.pl on that input file, which
+         generates an SVG Font file.
+
+      3. Using FontForge to convert that SVG Font file into a WOFF file.
