If you think these changes are worth committing, it might be better to submit this as a pull request.
For what it's worth though, I'm impressed you managed to capture that as a screenshot. You must have a very tall monitor :)

@countingpine They likely used a scrolling screenshot 😛 At least you can do that with ShareX

[rversteegen]

Firefox can take screenshots of page elements like that.

Anyway, this seems to be part of this commit:
skyfish4tb@0e4c0da
But it's mixed in with a lot of other changes.

@skyfish4tb,
Is skyfish4tb@0e4c0da the correct commit to be looking at?

The commit message says: "2. The optimization of [L/R]TrimAny function code."

Does the change fix problems? If yes, what were the failed cases?
Or this change is only an optimization?

I was working on some issues related to the wstring [L|R]TRIM functions in #142

Thanks.
