Maybe instead of
self assert: (codec decode: bom , self utf8String) asByteArray
= self decodedString asByteArray.
we need
self assert: (codec encode: (codec decode: bom , self utf8String))
= (codec encode: self decodedString).

That would be the same as #=, wouldn't it? Is comparing unicode
strings using #= not portable *if we know the two strings have the
same encoding* or at least were produced by the same codec?
