Short version:
No, to learn more either read the long version or scroll all the way down to the only known solution.
Long version:
Sadly Funcom decided to make the combat log in whatever language the client runs in, and that means you need to write a parser pr language. The problem here is simple, I dont speak / read French,German or Spanish so i cant write the parser.
Possible solutions:
1) Funcom adds a feature where the game can log to English while remaining UI and sound is in some other language, this is by far the best solution. So feel free to email/post in the Funcom forums regarding this.
2) Some 3dparty that knows either French,German or Spanish AND knows how to program in either c++ or C# contacts me and we can probably work on a solution.
Only known solution for now:
For the only option is run the SimpleConfig.exe tool in your Age of Conan folder and change the language to English.
