I've just downloaded the daily snapshot at http://svn.python.org/snapshots/python.tar.bz2

In the header file /python/Modules/unicodedatadb.h, there are the following lines in the changerecords320 struct: { 255, 255, 255, 255, 1.0 }, { 255, 255, 255, 255, 2.0 }, { 255, 255, 255, 255, 3.0 }, { 255, 255, 255, 255, 4.0 }, ... { 255, 255, 255, 255, 1e+16 }, { 255, 255, 255, 255, 1e+20 }, Looks like a bug to me. I don't think so. Unicode 3.2 did contain two entries with large numeric values. The file Unihan-3.2.0.txt contains these two lines: U+4EAC kPrimaryNumeric 10,000,000,000,000,000 ten quadrillion (American) U+5793 kPrimaryNumeric 100,000,000,000,000,000,000 hundred quintillion (American) For some reason newer versions of the unicode standard removed these values. It causes a type warning:

warning C4244: 'initializing' : conversion from 'double' to 'const int', possible loss of data
