java - UTF-8Characters not displayed correctly in -

we working on project school, project mandatory tri-lingual (dutch, english , french) , answer "change english not do".

all our classes , resource files encoded in utf-8 format, , alle non-standar english characters diplayed correctly in classes themself.

the problem once try display our text, alle non-standard english characters distorted.

we hear alot due encoding issue, sincerly doubt that, since our whole project encode in utf-8.

here extract french resource bundle:

videosettings = réglages du vidéo soundsettings = réglages du son keybindsettings = keybind paramètres languagesettings = paramètres de langue difficultysettings = paramètres de difficulté exitsettings = sortie les paramètres 

and results in these following displayed strings.

display result provided resourcebundle extract

i gratefull solution problem

edit

for info building desktop app using swing.

you didn't show code, read resource files. if use propertyresourcebundle inputstream in constructor, inputstream must encoded in iso-8859-1. in case, characters cannot represented in iso-8859-1 encoding must represented unicode escapes.

you can use native2ascii or anyedit tools convert properties unicode escapes, see use cyrillic .properties file in eclipse project
