# Perhaps something like them could be added if necessary. The JSN does have
# a real code point U+110B that maps to the null string, but it is a

# a, 'non_skip => 1,' in its constructor will be skipped.
#
+# To compare the output tables, it may be useful to specify the -annotate
+# flag. This causes the tables to expand so there is one entry for each
+# non-algorithmically named code point giving, currently its name, and its
+# graphic representation if printable (and you have a font that knows about
+# it). This makes it easier to see what the particular code points are in
+# each output table. The tables are usable, but because they don't have
+# ranges (for the most part), a Perl using them will run slower. Non-named
+# code points are annotated with a description of their status, and contiguous
+# ones with the same description will be output as a range rather than
+# individually. Algorithmically named characters are also output as ranges,

# FUTURE ISSUES
