Questions

How do I decode caret notation from a terminal dump?

Paste the visible caret or M-prefixed notation. The decoder converts recognized sequences into byte values. Use the byte result when you need control characters that normal text display can hide.

What do ^M and M- prefixes mean?

^M represents carriage return, byte 13. M- notation represents bytes with the high bit set. These terminal display conventions differ from backslash escapes such as \r or hexadecimal text such as 0d.

Does caret decoding restore every original terminal byte?

No. A text dump can contain literal characters that resemble encoded sequences. Keep the original dump and compare the decoded byte count. This operation interprets notation; it cannot recover information that the dump already lost.
