German messages have display problems on windows.

[ThomasGier]

Hello,

I have an issue with the output coming from LanguageTool not displaying correctly.
I'm using the German language, langtool 1.5.1 on Windows 8.1 with emacs 25.2 and LanguageTool 3.7.

The issue appears with umlauts and the "ß" character, as shown below (and probably unicode characters in other languages).

To fix the issue I took the second example from here and modified langtool as follows to switch java encoding to UTF-8:

diff --git a/langtool.el b/langtool.el
index 029bba4..b6aaad5 100644
--- a/langtool.el
+++ b/langtool.el

                            args))
       (setq args (append
-                  (list "-jar" (langtool--process-file-name langtool-language-tool-jar))
+                  (list "-Dfile.encoding=UTF-8"
+                        "-jar"
+                        (langtool--process-file-name langtool-language-tool-jar))
                   args)))
     (when langtool-mother-tongue
       (setq args (append args (list "-m" langtool-mother-tongue))))

Hi, thanks for the issue.

Please try process-custom-args branch

https://github.com/mhayashi1120/Emacs-langtool/tree/process-custom-args

and set:

(setq langtool-java-user-arguments '("-Dfile.encoding=UTF-8"))
