The solution to my issue was to install the font from the mod named `univers57.otf` and then when I was in Notepad++ I chose Setting -> Style Configurator -> Global Styles -> Default Style and chose the `Univers LT Std 57 Cn` and then the characters appeared in Korean properly in Notepad++. I used my in game helper tool (in Lua) to gather the quest names and save that to the saved vars file. I copied and pasted that into the language files.
Then I quit out of ESO, and loaded the game again and now things seem to display correctly.
I also feel like I was loosing the encoding. I used a website to sort the lines by numerical value. Come to find out in Notepad++ Under Line Operations is an option to Sort Lines as Integers. The way I have the text formatted (RegEx) allows Notepad++ to sort by the numbers, and then RegEx the lines into a table format again and I don't loose any encoding.
Now it seems to display properly in game. That was driving me crazy!
