| char secondChar state | char := converter nextFromStream: self.
converter is a UTF8TextConverter. Wondering if maybe I need a different text converter? Given that this is a CSV file, I'm thinking the system might be expecting UTF-8 where it's actually getting ASCII. The CSV package hasn't had any attention in a while, so that makes some sense (IIRC there was a shift to UTF-8 not very long ago, no?)
If anyone is wondering, I'm playing with an idea around dynamic data-centric web interfaces:) and need some raw data to represent, hence the CSV file.
Any ideas?

Try changing this to:
file := FileStream readOnlyFileNamed: 'myfile.csv'. file converter: Latin1TextConverter new. rows := CSVParser parse: file.

Haha! UI hangs and CPU spikes to the top; battery starts draining fast.

Only takes a couple of minutes, really. I suppose this is a question I'd have to ask eventually; is there a simple way to spin something like this off as a separate (green) thread, such that Morphic still responds while the job is running?

Sure. Try this:
[rows := CSVParser parse: file. SampledSound playSoundNamed: 'coyote'] forkAt: Processor userBackgroundPriority.
When the coyote howls, you're done :-)

... and since you presumably want to use that list for something, you need to get it back into Morphic. To safely talk from a background thread to your Morphic UI, use this:
[rows := CSVParser parse: file. WorldState addDeferredUIMessage: [myGUI updateList: rows]. ] forkAt: Processor userBackgroundPriority.
