File name char prefix used in training

Thanks for the fantastic work you've done with the deepseek-v2-lite-base!

I'm trying to verify if different chars were used as prefixes for the file names in Repository Level Code Completion. Here you have an example with Python where # is used to prefix utils.py. Is it recommended to use # for all the languages for the best FIM completions quality, or is it appropriate to use comment chars specific to the current languages (e.g., # for javascript)?
