osu.ppy.sh/scores/osu/xxx returns an odd score

[praeludiumOrbis]

As the title says, putting anything that doesn't start with numbers into https://osu.ppy.sh/scores/osu/xxx returns the above score

For example, https://osu.ppy.sh/scores/osu/h99h causes the behaviour, however with https://osu.ppy.sh/scores/osu/99h I get a "page missing" error.

Since the API always returns the same error, I am assuming that this is a website issue.

Other game modes give a similar result, although not on that map

This works with as many characters as you wish, including special characters and emojis:

Looks like some weird php best-effort casting. Probably should check for numeric and hard bail if not.
