Hi Jim!
I wonder why it was chosen to represent octal values as \[0-3][0-9][0-9]
| \[0-9][0-9] | \[0-9] ?
First, it will allow multiple leading zeroes.
Second, it does not require a leading zero, while, I think, many users
are used to octal numbers starting with a mandatory leading zero.
Was it considered to mirror the syntax from regex [1] ?

Hi Jim!
A few comments:
1)
Probably, there's no need to update ch in these cases:
case '\'':
ch = '\'';
break;
case '\"':
ch = '\"';
break;
True
2)
Character.digit(ch, 8) will accept non-Latin1 digits.
So, a sequence \\3\uFF17\uFF17 will be parsed as \\377.
(Note, that the first digit still can only be from range '0'-'9').
Also true. Subtlety in UnicodeReader.
3)
It's not obvious how this condition can be triggered:
if (0377 < code) {
throw new MalformedEscapeException(from);
}
I might be missing something, but I cannot see how 'code' can become
> 0377.
I removed this check in round 2.
4)
throw new MalformedEscapeException(from);
This will report the next index after the error. Was it intentional?
I switched to using an IllegalArgumentError and displaying the actual
character.
With kind regards,
Ivan
Much thanks.

Thank you.
