+"""
+This is a utility to 'can' the widths data for certain CID fonts.
+Now we're using Unicode, we don't need 20 CMAP files for each Asian
+language, nor the widths of the non-normal characters encoded in each
+font. we just want a dictionary of the character widths in a given
+font which are NOT 1000 ems wide, keyed on Unicode character (not CID).
+
+Running off CMAP files we get the following widths...
+>>> font.stringWidth(unicode(','), 10)
+2.5
+>>> font.stringWidth(unicode('m'), 10)
+7.7800000000000002
+>>> font.stringWidth(u'\u6771\u4EAC', 10)
+20.0
+>>>
