Google Text-to-Speech problem with French

I just discovered a problem with TTS conversion. I found this with french language but maybe it does the same also with other languages.

Generated audio replies contains strange pauses/bugs when there’s an apostrophe. See below.

• Text from the chatbot :
  “Bonjour ! En tant qu’IA, je n’ai pas d’émotions comme les humains, mais je suis toujours prêt à discuter et à répondre à tes questions. Comment puis-je t’aider aujourd’hui ?”
• Generated audio (listen to all the pauses when there’s a ” ‘ “) : https://we.tl/t-GGlOD3Qhbq

I tested the same voice models in the Google TTS console, with the same text, and it works well (without the strange pauses). So it means the problem is somewhere with the text format. Google TTS doesn’t recognize well the apostrophes sent by the plugin.
