Yes, the file format and game is UTF-8.
CGR should be mailing everyone with some info and tips about editing the CSV files early on Monday.
Notepad works; I've been told Notepad++ works; Excel works if you're careful with the UTF-8 import and export (see below). I think the plan is to use Google Docs, but this isn't fully tested yet.
The game should remember your EN/TN switch settings.
"WinMerge" is a good way to check that, when you edit a file, you're only changing the stuff you're intending to and not accidentally modifying the whole file. If you are using WinMerge, I think you need to set the file encoding to 65001 via the "File->File Encoding->Select Codepage for File Loading box (and use same codepage for both left and right)"
For Excel, I imported localization.csv into Excel 2016 via the text import wizard (again, making sure to set the "File Origin" encoding to 65001 Unicode (UTF-8)) I did some work. Then I did "Save As" and specified CSV UTF-8. For Excel, it is important to use the inport wizard, at least the first time around, to make sure you get the text in in the correct format.
If you're testing, I'd recommend you make a small change first, e.g., on the first screen, and check that it is working correctly.
Worst-case, provided *you* can read your CSV file in whatever you're using to modify it, CGR can probably work something out:)
Please don't re-order the CSV file, however: the game doesn't care about ordering, but retaining the original line-order will make it easier for CGR to work with the file. If you've already re-ordered stuff, that's fine, he can sort it out:)
