Developer releases Unicode string corpus to expose text handling flaws

By PulseAugur Editorial · [1 sources] ·

A developer has created a corpus of 300 Unicode strings designed to expose flaws in naive text handling functions, particularly `len()`. The corpus includes various complex Unicode features like ZWJ sequences and astral codepoints, with 20 cases provided for free under a CC0 license. The full dataset, available for purchase, aims to help developers identify how their text processing code behaves with user-pasteable strings, highlighting that simple tests like emoji handling do not guarantee comprehensive coverage. AI

IMPACT Highlights potential issues in LLM text processing and data handling, crucial for accurate model output and safety.

    300 Unicode strings where len() lies — 20 are free and scored in one Python file

    <p>I built a 300-case labelled corpus of Unicode strings that break naive text handling — combining marks, ZWJ sequences, astral codepoints, bidi controls, zero-width characters, homoglyphs, NFKC folds, case mapping traps, and exotic whitespace. Twenty cases are free (CC0). The r…
