Thanks Mitchell,

It looks like the thing that I was missing was connecting to the events.FILE_OPENED event. It now appears to be working.

I was under the impression that the init.lua file being applied to every buffer essentially meant that it would be applied to every opened file. I guess that is not the case?

Here is an example of what I am trying to achieve: I have a file with 256 bytes where the first byte is 0x00, then 0x01, and so on up to 0xFF as the last byte in the file. I would like to be able to open this file in TA and see blobs for bytes 0-31 and 128-255 with normal characters for everything in between. What I see for bytes 128-255 is essentially ISO 8859-1 representation (CP-1252) when buffer.encoding is nil. I suspect this would work as I expect on my Mac.

The status bar says the encoding is still CP862.
