How to Check CJK Text Style Consistency
When working with CJK (Chinese, Japanese, Korean) web content, it's common to find inconsistencies like fullwidth "ABC" mixed with halfwidth "ABC", or stray fullwidth spaces hiding in the text. These issues are nearly invisible to the naked eye but can affect professionalism and data integrity. This guide shows you how to use Text Style Checker to catch them quickly.
Common Style Inconsistencies
| Type | Incorrect | Correct |
|---|---|---|
| Fullwidth alphanumerics | Ｗｅｂ, １２３ | Web, 123 |
| Fullwidth spaces | テスト テスト | テスト テスト |
| Halfwidth katakana | ﾃｽﾄ | テスト |
Why Consistency Matters
- Maintains a professional, polished appearance for readers
- Can affect how search engines normalize and index your content
- Prevents character encoding issues when data is copied or exported
- Helps enforce consistent quality standards across a team
How to Use It
Step 1: Install
Install "Text Style Checker" from the Chrome Web Store.
Step 2: Open the page you want to check
Navigate to the page you want to audit — a draft article before publishing, a product description page, a press release, or any CJK content that needs to be consistent.
Step 3: Run the check
Click the extension icon in your toolbar and press the "Check Style" button. Detected issues are displayed with a count per rule and surrounding context for each match.
Step 4: Review and fix
- Summary overview: See the total count of fullwidth alphanumerics, fullwidth spaces, and halfwidth katakana detected
- Context view: Each match shows 20 characters of surrounding text, making it easy to locate the exact issue
- Clean result: If no issues are found, you'll see a "No issues detected" message
When to Check
- Before publishing articles or pages
- During periodic reviews of existing content
- When receiving drafts from external writers
- As part of quality assurance during a site redesign
