I just did a simple fix for two test failures in UTF16TextConverterTest and committed to inbox only to discover that there are several other versions waiting review. In particular Monty has submitted a substantial change. Let me ask that those people who understand the txt converter framework have a look at these proposals.
Another observation is that there are a couple of methods (UTF16TextConverter UTF32TextConverter) that do this:
swapLatin1EncodingByteOrder
latin1Encodings := latin1Encodings collect: [:each |
each ifNotNil: [each reverse]]
but reverse (quite rightly) isn't implemented in Squeak. It's meaningless. One needs to specify a byte size and reverse for that byte size, e.g. 1 reversed in UTF16TextConverter would be 256, but in UTF32TextConverter would be 16777216, right?
But since the latin1Encodings in both UTF16TextConverter UTF32TextConverter are (rightly) all nil these could just as well be implemented as ^self.
