Could those become enum values instead, which means you can store up to
255 different code-page types in 1 byte. 255 should be sufficient to
cover all available code-page constants (I think).

Or couldn't that maybe be reduced to 6 bits for code page enum values,
giving a total of 63 different values for code page types (still
sufficient I think). And then the remaining 2 bits for element size. So
total usage is still 1 byte.

Sorry, I'm a bit rusty on bit alignment issues. Any URL you can suggest
where I could read further about this?
