UTF-8 Encoding problem

[jcheron]

With this datas in MongoDb :

{  "code" : "Beer1", "descriptif" : "affichage de la liste des bières /beers (L'affichage de la bière n'affiche pas le brasseur associé)"}

The Http response given by restHeart does not seem to be interpreted as UTF-8 :

{"code":"Beer1","descriptif":"affichage de la liste des bières /beers (L'affichage de la bière n'affiche pas le brasseur associé)"

This is not a RestHeart bug, since on another computer, there is no encoding problem.

Would the RestHeart server use the default encoding of the java virtual machine?

Configuration :

• RestHeart 3.0.0
• MongoDb 3.4.1
• java 1.8.0_111

Hi @jcheron

just tried but it worked for me, it must be your http client that mess ups the strings...are you on windows terminal?

Hi @ujibang Did you see that I changed the initial message of the issue. This also works for me on some computers

[mkjsix]

You mentioned different computers: which operating systems?

[jcheron]

I tried on debian 8 and windows 10 => no problems

I have the problem on windows 7

Which does not mean that the problem is related to the operating system...

Is there a way to force the encoding in the configuration file ?

[mkjsix]

To me this sounds like a Java configuration issue on Windows 7, maybe you can try to force the JVM to use the UTF-8 file encoding by passing the following JVM parameter when starting RESTHeart:

-Dfile.encoding=UTF-8.

On Windows, you can also set a global environment variable for that, but beware it will affect all of your JVM processes:

By setting the (Windows) environment variable JAVA_TOOL_OPTIONS to -Dfile.encoding=UTF8, the (Java) System property will be set automatically every time a JVM is started. You will know that the parameter has been picked up because the following message will be posted to System.err:

Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF8

[jcheron]

Indeed, it depends on the jvm. Launching with -Dfile.encoding = UTF-8 solves the problem. Thank you ! It may be a parameter that could be included in the configuration file..

[mkjsix]

Hi @jcheron Indeed adding that parameter in the configuration file could be a good idea, I'll have a look into this.

[mkjsix]

I added "-Dfile.encoding=UTF-8" parameter to bin/start.sh

[jcheron]

This is what is called "be responsive". "être réactif" in French and with accents. I will test this (on my old win 7) Thank you @mkjsix
