I was basing my comment on the documentation:

Keyboard keys can be represented as integers. These are called key codes.
> You can use toCode and fromCode to convert between key codes and characters.


And the `Char.toKeyCode` function describes its purpose as:

Convert to key code.


But it turns out you're right, there is a simple conversion to integer
happening under the hood.

I think what I'm concerned about is that these strings may be treated as
Unicode and some unintentional conversion will happen without my knowing.
But I haven't tried yet.

Thanks for your help on this.

[elm-discuss] Convert Char to Int?

[Duane Johnson]

Big picture:

I'm writing a visual display algorithm of a binary ".hex" file that is the
result of compiling code on the Arduino platform. I load the file into the
browser via HTTP.getString, and then attempt to display the values.

Problem:

I'm unable to find a way to represent this binary data stream as a series
of 16-bit integers. I've attempted String.toList which results in a (List
Char) type, but what should I do with Char? Char.toCode and Char.fromCode
seem specifically tuned for use with keyboard events.

Is there a way to handle a binary data series in Elm?

Thanks,
Duane Johnson
