How do I match a specific ASCII code point?

I know that character ranges are a solved problem, but the parser does not accept single characters: "expected '..'". How can I make a rule that only matches the LF character? I tried this:

linefeed = { '\u{0A}' }

Sadly, according to your own testbed on pest.rs, this isn't a valid rule. What would be?

[tomtau]

linefeed = { "\n" }

or

linefeed = { '\u{0A}'..'\u{0A}' }

?

Thank you, the "one character range" works well. I still wonder whether it makes sense at all to enforce that.
