For once, I didn't need a special character for French words.
You see, this song was commissed by The Pokémon Company to commemorate 25 years of Pokémon. Why? Because Louane fit the fun image of Pokémon - in the words of Colin Palmer, vice president of marketing for The Pokémon Company International
“Louane is an exciting addition to the growing roster of talented artists from around the world helping us celebrate 25 years of Pokémon. Game Girl,’ with its French and English lyrics, is not only an amazing pop anthem for Pokémon Trainers, but also represents the global resonance of Pokémon with international fans.”
And, Louane - real name Anne Peichert - grew up playing the game. She did write this lighthearted, lovely pop song expressly for the occasion of the anniversary, with bilingual lyrics, both of which she sings without foreign accent in either, which takes talent. The song's title is clearly a play on the Nintendo Game Boy, for which several Pokémon games were quite popular.
The song will be included on Pokémon 25: The Album, released worldwide in October, so hopefully Louane will get some deserved attention outside of France, where she is a superstar.
