What is the problem?
If I search for an invalid title (such as one containing [ or <) I am taken to the title conflict step, told incorrectly that the article already exists and the continue button is greyed out.
I am not informed that my title contains invalid characters so I don't know how to fix it. I am not suggested a new title without those characters.
It also seems to have an impact on what suggestions you are shown (compare reproduction Case 1 with Case 2).
Steps to reproduce problem
Case 1
- https://test.wikipedia.org/wiki/Special:NewArticle?newarticletitle=[KHK2017]_165

Case 2

- Select the first option
- In this case, you are shown a suggestion of KHK2017 165 (Astronomical object)
