normality
Micro-library to normalize text strings
Decision gist · record as of 2026-08-14
Yes. Normality is a mature, actively maintained library with no known vulnerabilities, low install friction, and a permissive MIT license. It solves a concrete text-preprocessing problem with a small, focused API. Install it if you need to normalize Unicode text; avoid it only if pyicu is unavailable in your environment and you cannot use an older version.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Version 3.0+ requires pyicu, which may need system ICU libraries; if unavailable, use normality < 3.0.0.
- Low friction install with a pure-Python wheel.

What it is and what it does
Normality is a lightweight text-preprocessing library that applies a suite of Unicode normalization functions to prepare text for analysis. It removes diacritics (accents), punctuation, excess whitespace, and other character classes in a single pass, and can generate URL-safe slugs from arbitrary text. The package is built around a small set of composable functions—normalize, slugify, collapse_spaces, ascii_text, latinize_text—each handling a specific normalization task.
As of version 3.0, normality requires pyicu as a mandatory dependency, which brings full Unicode Collation Algorithm support but adds a system-level dependency. The package supports Python 3.10 through 3.13 and is actively maintained. It is useful as a preparation step for text analysis pipelines, search indexing, or any workflow where consistent text representation matters.
Use it for
- Normalize user-supplied text before indexing into a search engine or database.
- Generate URL-safe slugs from article titles or user-generated content.
- Clean and deduplicate text fields by removing diacritics and punctuation before comparison.
- Preprocess multilingual text for downstream NLP or machine learning tasks.
- Collapse irregular whitespace in scraped or imported text data.
