# The basic idea is to find named character references using binary
# search. Since entity strings may not have a terminator, this doesn't
# work if one entity string is a prefix of another. In this case,
# we branch to a subtable after matching the prefix.
#
# We create separate initial tables based on the first character
# of the entity name.
#
# The following tables are generated:
#
# htmlEntAlpha: start and end of initial tables, indexing into
# htmlEntValues
# htmlEntValues: concatenation of all table values, which index into
# htmlEntStrings
# htmlEntStrings: variable sized records containing entity name,
# replacement and optionally the position of a
# subtable
