Describe the issue
A clear and concise description of what the bug is.

When I checked the output of the MFA alignment, I found a case where some entities were changed to be different from the original text. The characters have changed from Simplified Chinese to Traditional Chinese. Here is the content from the .lab file:

霞浦县牙城镇乌岐，瓦窑村水位猛涨。

This is the output of the MFA alignment:

For Reproducing your issue
Please fill out the following:

1. Corpus structure
   • What language is the corpus in? mandarin
   • How many files/speakers? only 1
   • Are you using lab files or TextGrid files for input? .lab
2. Dictionary
   • Are you using a dictionary from MFA? If so, which one? I tried both mandarin_mfa and mandarin_china_mfa, but encountered the same issue.
   • If it's a custom dictionary, what is the phoneset?
3. Acoustic model
   • If you're using an acoustic model, is it one download through MFA? If so, which one? mandarin_mfa
   • If it's a model you've trained, what data was it trained on?

Log file
