Only one small change:
You can now use uni p 0d40 to get U+28 by decimal.
uni print 40 interprets the 40 as hex instead of decimal, and there was no way to get a codepoint by decimal number. Since codepoints are much more more common than decimals, leaving off the U+ and U is a useful shortcut I'd like to keep. AFAIK there isn't really a standard(-ish) was to explicitly indicate a number is a decimal, so this is probably the closest.
