Most of them are shell gotchas, and so would apply to rg

On Windows, if you want to match a line ending with $, then you have to use the --crlf option.

When enabled, ripgrep will treat CRLF (\r\n) as a line terminator instead of just \n.

I really wish this was enabled by default on Windows builds.

ripgrep at least won't suffer from the UTF-16 problem. It will automatically handle those files correctly by transcoding to UTF-8.
