in helix's source, there's a function called "char_is_line_ending"

```
/// Represents one of the valid Unicode line endings.
#[derive(PartialEq, Eq, Copy, Clone, Debug)]
pub enum LineEnding {
    Crlf, // CarriageReturn followed by LineFeed
    LF,   // U+000A -- LineFeed
    #[cfg(feature = "unicode-lines")]
    VT, // U+000B -- VerticalTab
    #[cfg(feature = "unicode-lines")]
    FF, // U+000C -- FormFeed
    #[cfg(feature = "unicode-lines")]
    CR, // U+000D -- CarriageReturn
    #[cfg(feature = "unicode-lines")]
    Nel, // U+0085 -- NextLine
    #[cfg(feature = "unicode-lines")]
    LS, // U+2028 -- Line Separator
    #[cfg(feature = "unicode-lines")]
    PS, // U+2029 -- ParagraphSeparator
}
```
