python-unicode-escape.el

Adds autocompletion for Python's \N{UNICODE NAME} string escape syntax in Emacs.

Completion is provided via completion-at-point (CAPF), making it compatible with company-mode (using company-capf), corfu, and the built-in M-TAB / C-M-i completion.

Features

• Standard CAPF: Works with any modern Emacs completion UI.
• Lazy Loading: The Unicode name database (~140k entries) is populated from Python on the first completion attempt in a session.
• Fast: Subsequent completions are instant using an internal cache.
• Annotations: Displays the actual character in the completion candidate list.
• Automatic Closing: Appends the closing } if it's missing.

Installation

Manual

1. Download python-unicode-escape.el and place it in your load-path.
2. Add the following to your init file:

(require 'python-unicode-escape)
(add-hook 'python-mode-hook #'python-unicode-escape-mode)

Requirements

• Emacs 27.1+
• python3 must be available in your PATH.

How it works

When you type \N{ and trigger completion, the package calls a small Python script to fetch all available Unicode names from the unicodedata module. This list is then cached for the duration of the Emacs session.
