There was a problem hiding this comment.
This could probably be optimized a bit more, perhaps checking for character codes instead of matching against a regex. But maybe JS engines are so smart these days that it doesn't matter. Did you ever benchmark path-parser?

@troch is this fix is supposed to be merged? I've faced an issue described here router5/router5#499 and also waiting for this MR to be resolved🙏 |

Hello!
I know this library is probably in kind of a "done" state but I noticed some issues with emojis in query params and decided to investigate. In the end it turned out the
.replacemethod breaks apart unicode characters in a way that will later trip upencodeURIComponent.Iterating over characters as done in this PR ensures that surrogate pairs are kept as-is and thus path building works as expected even when emojis are provided as part of path parameters.
(source)
I also added some tests to demonstrate that this is working as intended.
Cheers
