Solution:
Solution 1: menu-> Window-> Preferences-> General-> Content Types-> Text-> Java Properties File set Default encoding, change ISO-8859-1 to UTF-8 and then update. if it is a jsp file or other files can not be saved, you can also use the same method, select the appropriate type of file in Text, the following Default encoding, from the ISO-8859-1 to the UTF-8. Solution 2: If jsp can not save, you can set pageEncoding to UTF-8 on the line, for example: pageEncoding = "UTF-8" or Ctrl + F look for iso-8859-1, replace all the iso-8859-1 with a UTF-8.
