delta: UTF-8 problems on Windows

I’m finding that either delta or my terminal emulator is having a hard time with the non-ascii characters used for decorations. Long lines also don’t quite behave ideally. While I think delta is somehow the problem here, I’m not really sure, but I figured it would be good to at least file an issue in case anyone else encounters a similar problem. Even if I’m wrong, if someone could point me in the right direction, I’d appreciate it.

Assorted pertinent information:

• Running in the latest version of MSYS2 mintty on Windows 8.1
• I am using the version of less that comes with MSYS2; unsure if that is the same as what git-for-windows ships with.
• I installed both delta and bat via cargo, and neither are aliased.
• My bat config file contains only custom --map-syntax flags

Regardless of the value of core.pager:

Raw git diff for an arbitrary git-managed file: (for now, only the first few lines of it, because that’s really all I expect will be needed and the whole thing is just over 200 lines)

---

Without any value set for core.pager:

Side note regarding the width

I know that the issue with the width can be handled with git diff .inputrc | delta -ns --width="$(tput cols)", but that still doesn’t provide any means of displaying parts of a line that continue off screen. The complete text of line 49 reads # If enabled, lists all matches in case multiple possible completions are possible.. Please just disregard how odd “possible completions are possible” sounds.

---

After git config --global core.pager=delta, the first few lines of git diff .inputrc are shown as: and just for good measure, after adding to my global gitconfig

[delta]
	features = side-by-side line-numbers
	syntax-theme = Monokai Extended
[delta "line-numbers"]
	line-numbers = true
[interactive]
	diffFilter = delta --color-only

It only gets worse and either way, there’s still that little detail regarding the parts of the line that aren’t initially shown. Oh yeah, as I was getting screenshots and writing out this issue report, I discovered that trying to pipe either git diff .inputrc | delta or git diff .inputrc(with the previously mentioned gitconfig settings applied) through programs like head or tail only seems to pass along the default git diff output; not sure if that’s supposed to happen.
