Overview

Passthrough spell checker for languages that don’t use spell checking.

This checker always returns that words are “found” (correct). It’s used for languages that don’t have traditional spell checking, such as:

  • CJK languages (Japanese, Chinese) - use confusion rules instead

  • Languages with purely rule-based checking

Examples:

checker = PassthroughSpellChecker.new
result = checker.check('任意のテキスト')
# => { found: true, stem: nil, flags: [] }

Getting suggestions (always empty)

suggestions = checker.suggest('テキスト')
# => []
