Feature request: Change default decoded text encoding to ASCII

[SonOfLilit]

The "decoded text" window is used mostly to make plaintext sections in binary files easy to spot.

By using (I think?) latin1 as the encoding, it is much harder to distinguish at a glance between noise that includes happens to include a lot of characters that look like text (many values >127 happen to look like characters in latin1).

Many have asked already to add an option to switch encoding to e.g. UTF8, Shift-JIS or whatever they happen to need. My request is that the default be set not to latin1 but to ascii, the encoding used by most hex editors and for good reason (with all non-printable characters displayed as dots, perhaps in a different color to distinguish from real dot characters).

We currently just use String.fromCharCode which doesn't really have an encoding but instead returns the unicode character see https://unicode-table.com/en/.

We considers 0-32, 127-161, 173-174, and 256+ as unprintable.

Will you accept a pull request that considers all >127 as unprintable?

I reviewed the other allowed characters and I understand where you're coming from. I went ahead and pushed it so printable characters are in the range [32, 127). We still display the UTF-8 and UTF-16 representations in the data inspector.
