Normally, regexps understand `[a-z]` as a "range of characters with codes between codes of `a` and `z`.
But without `u` flag, surrogate pairs are assumed to be a "pair of independant characters", so `[𝒳-𝒴]` is like `[<55349><56499>-<55349><56500>]` (replaced each surrogate pair with code points). Now we can clearly see that the range `56499-55349` is unacceptable, as the left range border must be less than the right one.
