Detecting RLO character in Python

Read Original

The article explains a practical security issue where the Right-to-Left Override (RLO) Unicode character is used to disguise malicious files (e.g., making .exe appear as .doc). It details a Python solution using the unicodedata.bidirectional() method to scan filenames and detect the presence of the RLO character to block such uploads.
