summary

Covers practical abuses of Unicode that hide or disguise code and filenames, naming specific techniques such as homoglyphs (e.g. Cyrillic е vs Latin e), bidirectional (bidi) control characters that reorder displayed text to hide code inside comments, invisible characters that make different strings look identical, and filename tricks that disguise executables as documents. References the Trojan Source research by Boucher and Anderson and mentions related Python implications (PEP 672).
