Backspace not handled correctly

[vegas503]

In term library (& fyneterm app as well), hitting backspace produces ^H.

$ stty -a | grep erase
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
werase = ^W; lnext = ^V; discard = ^O; min = 1; time = 0;

...seems like the shell is expecting 0x7F, but fyne term is sending ^H (0x08).

I could reproduce this with both local shell (/bin/sh) as well as with connection (reader/writer).

This could be solved by exposing some functions to override special key codes that are emitted by fyne term on user input.

Sending 0x7F instead of 0x08 fixes my issue but requires patching fyne term code:

// input.go
// TypedKey will be called if a non-printable keyboard event occurs
func (t *Terminal) TypedKey(e *fyne.KeyEvent) {
	// ...
	case fyne.KeyBackspace:
-		_, _ = t.in.Write([]byte{asciiBackspace})
+		_, _ = t.in.Write([]byte{0x7F})

It sounds like you are missing up backspace and delete.
Both work correctly in my testing (bash, zsh, fish).

Can you confirm why your shell is expecting the DEL code when BS is tapped?
