@Shay Ben-Elazar Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
Azure Translator service does not support automatically adding diacritics to translated text as a built-in feature. Diacritics are typically considered as part of the specific language's orthography and are not automatically added during translation.
Azure Translator does provide features like Custom Translator, which allows you to create customized translation models. This could potentially be used to handle domain-specific terminology or language nuances such as diacritics. But this would require additional work and expertise in machine learning and natural language processing.
This won't be a direct approach though.

Alternatively, you can try to achieve the diacritics functionality by implementing a post-processing
step after translation. You would need to use some additional text processing or language-specific libraries to add diacritics based on the language of the translated text.
Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
