Inspectors

String Inspector

Paste a string and get detailed statistics about it. The tool shows character count, word count, line count, byte count (UTF-8), and Unicode code point count. These counts can differ — an emoji is one character but multiple bytes and multiple code points — so the tool breaks them all out separately. Useful for debugging encoding issues or checking string length limits.

String Inspector — Inspect length, words, lines, bytes and unicode code points

What it does

  • ▸Counts characters (including multi-byte characters like emoji)
  • ▸Counts words, lines, and sentences
  • ▸Counts UTF-8 bytes (how much storage the string actually uses)
  • ▸Counts Unicode code points (some characters are multiple code points)
  • ▸Shows the Unicode category of each character (letter, digit, symbol, etc.)

Use cases

  • ▸Checking if a string fits within a database column or API field limit
  • ▸Debugging encoding issues where character count and byte count differ
  • ▸Counting words in a document or text for content analysis
  • ▸Inspecting how emoji and special characters affect string length

How it works

1

Paste your string into the input pane

2

The tool computes all statistics instantly

3

Character, word, line, byte, and code point counts are displayed

4

Review the breakdown to understand the string's composition

Frequently asked questions

1Why do character count and byte count differ?

Characters are counted by Unicode code units (UTF-16), while bytes are counted in UTF-8 encoding. An emoji like 😀 is 2 characters (surrogate pair in UTF-16) but 4 bytes in UTF-8. The tool shows both so you can understand the actual storage and display implications.

2What are Unicode code points?

Code points are the fundamental units of Unicode — each one is a unique number assigned to a character. Some visible characters (like emoji with skin tones or family emoji) are composed of multiple code points joined by zero-width joiners. The code point count may differ from the character count for these.

3Can I use this to check Twitter/X character limits?

Yes. Social platforms typically count by Unicode code point or grapheme cluster, not by bytes. The character count shown here is a good approximation, though platform-specific counting may vary slightly.
