CJK & Latin Character Counter
CJK & Latin Character Counter: Scans codepoints against CJK Unified Ideographs, Hiragana, Katakana, and Latin script Unicode blocks.
About this cjk & latin character counter
CJK & Latin Character Counter — browser-based utility.
How this tool works
Implements client-side CJK & Latin Character Counter operations. Scans codepoints against CJK Unified Ideographs, Hiragana, Katakana, and Latin script Unicode blocks specifically designed for a localization editor breaks down text containing mixed english, chinese, and japanese kana characters.
- Codepoint Script Partitioning: Inspects each character's Unicode block, classifying codepoints into CJK ideographs, kana, punctuation, or Latin alphabets.
- Dictionary-Based Lexicon Mapping: Applies OpenCC contextual phrase dictionaries to accurately convert multi-character idioms between Traditional and Simplified Chinese.
- Pinyin & Phonetic Synthesis: Matches CJK characters to phonetic syllables, adding tone diacritics (ā, á, ǎ, à) or tone numbers.
- Width Normalization: Maps full-width alphanumeric glyphs and punctuation to standardized half-width ASCII equivalents.
Worked example
Scenario: A localization editor breaks down text containing mixed English, Chinese, and Japanese kana characters.
Sample input:
Processing: Scans codepoints against CJK Unified Ideographs, Hiragana, Katakana, and Latin script Unicode blocks.
Illustrative output:
Limits and verification
Polyphonic Chinese characters (characters with multiple contextual pronunciations, such as '行' as xíng or háng) use the most common frequency reading unless disambiguated by multi-character compound phrases in the dictionary.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
What categories does CJK Character Counter report?+
It counts Chinese ideographs, kana, Hangul syllables, Latin letters, digits, whitespace, punctuation, and the total number of Unicode code points in the input.
What did the browser fixture verify?+
For 中文あア한 A1!, it returned two Chinese characters, two kana, one Hangul, one Latin letter, one digit, one whitespace, one punctuation mark, and total nine.
How is the total different from a UTF-16 string length?+
The tool spreads the input into Unicode code points before counting, so each iterated character contributes one total even when JavaScript UTF-16 storage would use surrogate code units.
Does the counter identify every writing system?+
No. Its dedicated categories cover the listed ranges; other letters are absent from those language-specific counters, although they still contribute to total and may affect punctuation classification.
