When the processing reaches the line that contains the NUL an exception is raised. I'm wondering if there is something that can be done in `sqlite-utils` to say ""skip lines with encoding errors"" or some such. I think it isn't super straightforward though as the exception comes from inside the `csv` module that does all the parsing. Concretely the file is the `KernelVersions.csv` from https://www.kaggle.com/datasets/kaggle/meta-kaggle This is the command and output: ``` $ sqlite-utils insert --csv kaggle.db kaggle KernelVersions.csv [------------------------------------] 0% [#####################---------------] 60% 00:04:24Traceback (most recent call last): File ""/home/foobar/miniconda/envs/meta-kaggle/bin/sqlite-utils"", line 10, in sys.exit(cli()) File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/click/core.py"", line 1128, in __call__ return self.main(*args, **kwargs) File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/click/core.py"", line 1053, in main rv = self.invoke(ctx) File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/click/core.py"", line 1659, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/click/core.py"", line 1395, in invoke return ctx.invoke(self.callback, **ctx.params) File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/click/core.py"", line 754, in invoke return __callback(*args, **kwargs) File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/sqlite_utils/cli.py"", line 1223, in insert insert_upsert_implementation( File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/sqlite_utils/cli.py"", line 1085, in insert_upsert_implementation db[table].insert_all( File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/sqlite_utils/db.py"", line 3198, in insert_all chunk = list(chunk) File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/sqlite_utils/db.py"", line 3742, in fix_square_braces for record in records: File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/sqlite_utils/cli.py"", line 1071, in docs = (decode_base64_values(doc) for doc in docs) File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/sqlite_utils/cli.py"", line 1068, in docs = (verify_is_dict(doc) for doc in docs) File ""/home/foobar/miniconda/envs/meta-kaggle/lib/python3.10/site-packages/sqlite_utils/cli.py"", line 1003, in docs = (dict(zip(headers, row)) for row in reader) _csv.Error: line contains NUL ```",140912432,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/582/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,
