GRPlatform current secureHashFor: depends on the used String class

Marten,

this should be true on any platform. The hash is computed on a string of bit octets, IOW, binary values. The default encoding is probably going to be UTF-8, so the binary representation of the two string will be different, and therefore the hash. I don’t see any way around it other than forcing the default encoding to be UTF-16 which I don’t know how Grease handles in GLASS.

I do not know, if this is an error - but I notice that secureHashFor: is based on the byte representation of the used string:

GRPlatform current secureHashFor: 'vorzimmer' = GRPlatform current secureHashFor: (Unicode16 withAll: 'vorzimmer' )

is false ....

Yes, but this should be made *very* clear in the documentation ...

I think one could make a valid argument that the code points should be the source of the bits. e.g. ASCII characters in a Unicode16 string would only have their ASCII code points used, not the internal representation bits.
