 # Script to tidy up the output of w3m when it makes a text file. First we
 # convert sequences of blank lines into a single blank line, to get everything
 # uniform. Then we go through and insert blank lines before chapter and
 # sections, also converting chapter titles to uppercase.
 
+# We also have to do some character translation in the first pass. It seems
+# that xmlto now generates Unicode in its HTML pages. This gives three problems:
+# (1) It inserts the byte sequence C2 A0 (U+00A0) as a fixed-width space;
+# (2) It inserts a whole slew of "box drawing" characters round the heading.
+# (3) It uses U+25CF as its bullet character.
