Nope. Here is a demo:
---------
import string

# a (0061, 61), combining diaeresis (0308, CC 88), a with diaeresis
# (00E4, C3 A4), euro (20AC, E2 82 AC)
# 23763 (D84D + DF63, F0 A3 9D A3)

testStr = "\141\314\210\303\244\342\202\254\360\243\235\243"

testUString = unicode(testStr, 'utf-8')
	
for c in testUString:
	print "%X" % ord(c)
---------

That's a self-contained program that produces different output  
depending on how the interpreter was compiled.

It matters for any program that looks inside the strings.

It is. See above.
