"Hi Tobias,

Strings in Squeak are either ByteString or WideString based on the Unicode
codePoints of their characters.
Strings are instances of ByteString if they contain characters with
codePoint < 256.
And instances of WideString if they contain characters with codePoint >=
256.

$A codePoint = 65.

tmpString1 := String with: $A.
tmpString1 class = ByteString.
tmpString1 size = 1.

tmpString2 := String with: (Character codePoint: 269).
tmpString2 class = WideString.
tmpString2 size = 1.

tmpString3 := tmpString1, tmpString2.
tmpString3 class = WideString.
tmpString3 size = 2.

tmpString4 := tmpString3 copyFrom: 1 to: 1.
tmpString4 class = ByteString.
tmpString4 size = 1.

tmpString5 := tmpString2 squeakToUtf8.
tmpString5 class = ByteString.
tmpString5 size = 2.

tmpString6 := tmpString5 utf8ToSqueak.
tmpString6 class = WideString.
tmpString6 size = 1.



"The national characters mentioned have Unicode codePoint >= 256.

When importing a Unicode font,
the guard
	i < 256 ifTrue: []
in
	TTFontReader>>#decodeCmapFmtTable:
discards all characters
with Unicode codePoint >= 256.

This is undesirable as all those characters mentioned have codePoint >= 256.

The guard
		value > 65535 ifFalse: [ ]
in
	TTCFontReader>>#processCharMap:
discards all characters
with Unicode codePoint > 65535.

This is required as
glyphs size = 65536
.

Most languages have characters with codePoint <= 65535 so this should not be
a problem.

Best Regards,
Milan
