UCS-4 is technically only a 31-bit encoding. The sign bit is not used,

How is this a bottleneck? If you removed the Latin-1 encoding
altogether and limited the flexible representation to just UCS-2 /
UCS-4, I doubt v
not the relative size of the string data. Again from the
comments:
Compact strings use only one memory block (structure + characters),
whereas legacy strings use one block for the structure and one block
for characters.

Try using a set here instead of a list:
extensions = set()
for filename in filenames:
f = open(filename, "w")
f.write("Some text\n")
f.close()
name , ext = os.path.splitext(f.name)
extensions.append(ext)
and use:
extensions.add(ext)
This should take care of duplicates for you.
