Unicode Glyph & Codepoint Inspector
Lists each character and its Unicode code point, decimal value, and a broad ASCII/Unicode label. It does not show UTF-8 bytes, UTF-16 units, or formal Unicode names.
About this unicode glyph & codepoint inspector
Lists each character and its Unicode code point, decimal value, and a broad ASCII/Unicode label. It does not show UTF-8 bytes, UTF-16 units, or formal Unicode names 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: Inspect one ASCII character and one non-BMP emoji by JavaScript code point.
Sample input:
Processing: Iterate JavaScript code points and emit each glyph, uppercase U+ label, decimal value, and the broad ASCII or Unicode glyph hint.
Illustrative output:
Character encoding & string length boundaries
No formal character names, grapheme-cluster analysis, UTF-8 bytes or UTF-16 units are provided.
Text formatting and transformations in Unicode Glyph & Codepoint Inspector 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 Unicode Glyph & Codepoint Inspector execute entirely in local browser memory without transmitting input text.

Frequently asked questions
What information does Unicode Glyph and Codepoint Inspector return?+
It returns a JSON array with one record per JavaScript code point: `glyph`, uppercase `codePoint`, decimal, and `nameHint`.
Does one visible emoji always produce one record?+
No. The tool iterates code points rather than grapheme clusters, so a visible emoji or combined letter can yield multiple records for modifiers, joiners, or variation selectors.
Does it show UTF-8 bytes or official Unicode names?+
No. `nameHint` is only `ASCII` below 128 and `Unicode glyph` otherwise.
Can I try a concrete input?+
Enter `A🙂`. The JSON has two records: `A` with `codePoint` `U+0041` and decimal 65, then `🙂` with `codePoint` `U+1F642` and decimal 128578.
