31: # This file contains a table driven entity-->latex converter.
32: #
33: # Assumptions:
34: # The number of entities in a resource is small compared with the
35: # number of possible entities that might be translated.
36: # Therefore the strategy is to match a general entity pattern
37: # &.+; over and over, pull out the match look it up in an entity -> tex hash
38: # and do the replacement.
39: #
40: # In order to simplify the hash, the following reductions are done:
41: # &#d+; have the &# and ; stripped and is converted to an int.
42: # &#.+; have the &#x and ; stripped and is converted to an int as a hex
43: # value.
44: # All others have the & and ; stripped.
45:
46:
47: # The hash: Add new conversions here; leave off the leading & and the trailing ;
48: # all numeric entities need only appear as their decimal versions
49: # (e.g. no need for 1234 is sufficient, no need for 0x4d2 as well.
50: #
51: # This entity table is mercilessly cribbed from the HTML pocket reference
52: # table starting at pg 82. In most cases the LaTeX equivalent codes come from
53: # the original massive regular expression replacements originally by
54: # A. Sakharuk in lonprintout.pm
55: #
56: # I also want to acknowledge
57: # ISO Character entities and their LaTeX equivalents by
58: # Vidar Bronken Gundersen, and Rune Mathisen
59: # http://www.bitjungle.com/isoent-ref.pdf
60: #
61:
62: # Note numerical entities are essentially unicode character codes.
