Are spaces wrapped too?

No, whitespace characters are left exactly as they are; only non-space characters get wrapped in the symbol pair, which keeps multi-word input readable.

Can the opening and closing symbols be different lengths or strings?

Yes, they're independent fields, so you could use " ", "((" and "))", or any other pair, not just single matching brackets.

Does it handle multi-byte characters like emoji correctly?

Yes, it splits the input using code-point-aware iteration rather than raw UTF-16 units, so most emoji and other multi-byte characters are wrapped as single characters rather than being split apart.

Letter Symbol Wrapper - Wrap Every Character in Symbols

Overview

Introduction

Wrapping every letter of a word in brackets or another symbol pair creates a distinctive, highly decorative look that's slow to type by hand.

This tool applies that wrap to every non-space character in your text automatically.

What Is Letter Symbol Wrapper?

A tool that walks through your text character by character and surrounds every non-space character with a chosen opening and closing symbol pair.

It runs entirely client-side as part of this site's String Tools collection, so nothing you paste is ever uploaded to a server.

How Letter Symbol Wrapper Works

The tool splits the input into individual characters (code-point aware, so most multi-byte characters stay intact), and for every character that isn't whitespace, wraps it between the opening and closing symbol, leaving whitespace untouched.

The transformation happens synchronously in JavaScript the moment you type, with no network round trip involved.

When To Use Letter Symbol Wrapper

Use it to create a highly decorative, boxed-letter text effect for a heading, or to build a per-character tagging format for a custom parser.

It's a fast way to get the answer without opening a code editor, a REPL, or writing a one-off script just to check.

Often used alongside Letter Symbol Inserter, Word Symbol Wrapper and Word Symbol Unwrapper.

Features

Advantages

Opening and closing symbols are independently configurable, not limited to matching bracket pairs.
Leaves spaces unwrapped, keeping multi-word phrases visually separated.

Limitations

Output grows quickly for longer text, since every non-space character gains two extra symbol strings around it.

Examples

Wrapping letters in square brackets

Input

hi

Output

[h][i]

Each of the two non-space characters is wrapped individually with the default "[" and "]" symbols.

Best Practices & Notes

Best Practices

Keep the input short for the most legible decorative effect, since the wrapped output is significantly longer than the original.
Use single-character symbols like "["/"]" or "("/")" for the cleanest boxed-letter look.

Developer Notes

Splitting uses Array.from(input) rather than input.split("") for code-point-aware iteration, and each character is tested with /\s/.test(char) to decide whether to leave it unwrapped, so whitespace of any kind (space, tab, newline) is preserved as-is.

Letter Symbol Wrapper Use Cases

Creating a boxed-letter decorative heading or banner
Building a per-character tagging format for a custom parser or teaching tool
Producing a visually distinctive stylized version of a short word or acronym

Common Mistakes

Leaving either the opening or closing symbol field empty, which the tool rejects since both are required to form a pair.
Running it on long text and being surprised by how much longer the wrapped output is.

Tips

For a lighter-weight effect that doesn't double the symbol count, try the Letter Symbol Inserter tool, which places a single symbol between characters instead of wrapping each one.
