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.
