I found one more case where UTF-8 had to be specified and I made it explicit in all the remaining file accesses I could find. While I'm glad UTF-8 is default in Files.newBufferedReader(), the fact that Java has for so many years assumed that "no charset" implies "system default" means the people reading the code are potentially going to be confused if it's omitted, so I just added it consistently everywhere.
