About this cjk & latin character counter

Counts selected BMP Han, kana and Hangul ranges, ASCII letters, digits, whitespace and punctuation, and reports their counts with a Unicode code-point total Applies Unicode-compliant text transformations and parsing directly in the browser tab without data leakage.

Text processing & transformation mechanics

Processes East Asian and multi-script typography adhering to Unicode Standard Annex #11 (East Asian Width), the OpenCC standard for Traditional and Simplified Chinese dictionary mapping, and Hanyu Pinyin phonological romanization tables. Distinguishes between CJK Unified Ideographs (U+4E00 to U+9FFF), Hiragana, Katakana, Hangul, and Latin characters. Converts full-width ASCII characters (U+FF01 to U+FF5E) to half-width equivalents and resolves multi-character contextual idiom variants.

Worked text manipulation example

Scenario: Classify a short mixed-script string using the counter's fixed character ranges.

Sample input:

CZOA 工具 (Tokyo 開発 2026)

Processing: Iterate Unicode code points and test the fixed BMP Han/Kana/Hangul, ASCII, whitespace and punctuation ranges.

Illustrative output:

{ "chinese": 4, "kana": 0, "hangul": 0, "latin": 9, "digits": 4, "whitespace": 4, "punctuation": 2, "total": 23 }

Character encoding & string length boundaries

Supplementary ideographs and non-ASCII Latin letters are not included in their named category counts; total counts Unicode code points, not grapheme clusters.

Text formatting and transformations in CJK & Latin Character Counter preserve character integrity. Check edge cases such as multi-line inputs and special characters before downstream use.

In-memory text processing boundary

String operations and Unicode manipulations in CJK & Latin Character Counter execute entirely in local browser memory without transmitting input text.

Unicode Consortium & text formatting standards

Unicode Consortium standard annexes (UAX) and character encoding specifications:

  • ECMAScript Unicode code-point iteration, selected BMP Han/kana/Hangul ranges, and Unicode punctuation property.
  • Fixed tool categories; supplementary Han, accented Latin and symbols may contribute to total without entering a named category. No fixed Unicode-version claim.

Frequently asked questions

What does this character counter classify?+

It iterates Unicode code points and reports separate counts for Chinese BMP code points `U+3400`–`U+9FFF`, Kana, Hangul, ASCII letters, digits, whitespace, punctuation, and total code points.

What local example can I run?+

Enter `A中あ한1 !` → Chinese 1, Kana 1, Hangul 1, Latin 1, digits 1, whitespace 1, punctuation 1, total 7.

Does it count every Han character as Chinese?+

No. The Chinese bucket is only the BMP ranges `U+3400`–`U+9FFF`; for example, Extension-B `𠀀` is not in that bucket, though it still contributes to total.

Does it identify language or text meaning?+

No. It classifies individual code points. Accented Latin letters and many other scripts are not ASCII Latin in this tool.
