描述
Summary:
Many users of PapaParse may encounter CSV files that contain pre-escaped characters. In the current implementation, PapaParse automatically adds escaping to these characters, which results in double-escaped characters in the output. This behavior can be problematic for CSVs that are expected to contain escape characters as part of the data.
Issue:
When parsing a CSV with pre-escaped quotes (either with a backslash or double quotes), PapaParse's parser automatically escapes these characters, leading to an unexpected doubling of escape characters in the output.
For example, an input CSV line like:
"Test \"Test string\" Test","Definitely \"real\" cash"
gets parsed to:
["Test \\\"Test string\\\" Test", "Definitely \\\"real\\\" cash"]
instead of the expected:
["Test \"Test string\" Test", "Definitely \"real\" cash"]
Similarly, a value enclosed in triple quotes to signify an internal quote like:
"""Test \"Test string\" Test"""
results in:
["\"Test \\\"Test string\\\" Test\""]
which should ideally remain:
["""Test \"Test string\" Test"""]
Feature Request: It would be beneficial to have an option to disable auto-escaping entirely when parsing CSV files. This would allow users to work with CSV data that already includes the necessary escaping and expects it to be preserved as-is.
