If the core uses specific 8bit values for the internals then there is a hope and
prayer.
E.g. "blob" would need to be char _BLOB={0x62,0x6c,0x6f,0x62} because the hash
calculation would be wrong if were {0x82,0x93,0x96,0x82} ensuring the compiler
does not change that "binary" data value.

And then all output would require code-page aware translation, but fix the above
first.
