New submission from Gianluca <gianluca.gippe...@gmail.com>:
When bz2 and lzma files are used in writing text mode (wrapped in a TextIOWrapper), the BOM of encodings such as utf-16 and utf-32 is not written. The gzip package works as expected (it writes the BOM). The code that demonstrate this behavior (tested with Python 3.7) is attached here and can also be found on stackoverflow: https://stackoverflow.com/questions/55171439/python-bz2-and-lzma-in-mode-wt-dont-write-the-bom-while-gzip-does-why?noredirect=1#comment97103212_55171439 ---------- components: IO files: demonstrate_BOM_issue.py messages: 337987 nosy: janluke priority: normal severity: normal status: open title: When using bz2 and lzma in mode 'wt', the BOM is not written type: behavior versions: Python 3.7 Added file: https://bugs.python.org/file48209/demonstrate_BOM_issue.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36304> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
