Good question :)
What IS the presumed internal encoding of Bytestrings in Squeak?
That's the one I meant, I merely assumed it was latin1 seeing as how the text converter refers to it as such.
Personally I thought it was iso8859-L1, seeing as the bytestring to unicode conversion does a simple shift of chars > 127 to the 0080 - 00FF range.

From what I understood, CP1252 is Microsoft "latin1" and use codes 128 to 159.
ISO8859-L1 match fisrt 256 codes of unicode latin-1 and has codes 128
to 159 unused.
You know, when Microsoft "uses" a standard, it's always a better standard ;)

I have nothing against CP1252, it's an optimization which avoid
wasting 32 cheap codes.
But I'm not sure about various compatibility issues in/with the
external world...

If you know how to easily assure that

(String with: (Character value: (Integer readFrom: '20AC' base: 16))) = (String with: (Character value: (Integer readFrom: '80' base: 16)))

than you might be safe. By using Windows-1252 code points aren't unique anymore. Every code point in the range 0x80 - 0x9F exists somewhere else, too. So my estimation would be that it will cause more trouble than it might solve.

Squeak clearly uses CP1252.
For Pharo, there might be a mix of the two since Sophie-like
refactorings. Surely what John was refering to.
In pharo the 20AC string gives me a euro sign but the 80 hex one prints a rectangle which is _a_ interpretation of '?' ;)
