Notes

• The translated epub file will be named [original_file]_translated.epub and located in the same folder as the original epub file.
• Suported destination languages are shown in LANGUAGES variable in the epub-translator.py file.
• This tool uses autodetect source languages when translating. If you have a problem with it, contact me and maybe I will add the manual select source languages.

Issues

• I only tested the tool on some of my favorite books and light novels. 
• This tool may be buggy. Some books may crash with complex epub structure or some of the text will not be translated.
• Sometimes, too many translation requests to the Google Translate API may cause Google to ban your IP from getting its translation service shortly. If this happens, you should change your IP via VPN.
