Describe the bug

import phonemizer as ph
from phonemizer.separator import Separator
 phonemized = ph.phonemize(lines, language_switch='remove-flags', separator=Separator(phone='-', word=' '),preserve_punctuation=True)

    if filename == "<" + filename[1:-1] + ">":
RecursionError: maximum recursion depth exceeded in comparison

Phonemizer version 3.1.1

System linux

Expected behavior len(lines) >= 2000 when i don't set preserve_punctuation=True, it works; when i set preserve_punctuation=True,if produce exceeded error;

Hi @sunnnnnnnny. The latest master has fixed the punctuation recursion error. I'm not sure when the next release is coming, but for now the current master should solve your problem.
