Unicode Superscript & Subscript: Complete Beginner-to-Advanced Guide

Unicode superscript & subscript characters play a crucial role in modern digital writing. From chemistry formulas like H₂O and physics equations such as E = mc² to academic references, mathematical expressions, and styled social media text, superscript and subscript formatting is everywhere.

This complete guide explains what Unicode superscript & subscript are, how they work, why Unicode is better than HTML formatting, where these characters are supported, their limitations, and why using an online Unicode generator is the most reliable solution.

Whether you’re a student, researcher, developer, blogger, or content creator, understanding Unicode superscript and subscript will help you format text correctly across all platforms.

Unicode is a universal character encoding standard that assigns a unique code to every character, symbol, letter, and number used in digital text. Its purpose is to ensure that text appears consistently across all devices, operating systems, browsers, and applications.

Before Unicode, text encoding varied by platform and language, often causing symbols to break, appear incorrectly, or turn into unreadable characters. Unicode solved this problem by creating a single, global standard.

Today, Unicode supports:

• Letters from all major languages
• Mathematical symbols
• Currency signs
• Emojis
• Superscript and subscript characters

Because Unicode is platform-independent, text encoded using Unicode works reliably in Google Docs, Microsoft Word, WordPress, HTML content, PDFs, emails, and social media platforms.

Many people use HTML tags like <sup> and <sub> to create superscript and subscript text. While this works inside web pages, it has serious limitations.

Unicode vs HTML Superscript & Subscript

1. HTML formatting:
   • Only works inside HTML-supported environments
   • Breaks when copied into documents, emails, or social media
   • Requires coding knowledge
   • Often loses formatting when pasted elsewhere
2. Unicode superscript & subscript:
   • Are actual characters, not visual styling
   • Work everywhere Unicode is supported
   • Stay formatted when copied and pasted
   • Require no HTML or CSS

For example, HTML superscript like <sup>2</sup> may look correct on a webpage but will lose formatting when pasted into Google Docs or a social media bio. Unicode superscript ², on the other hand, remains intact everywhere.

This is why modern tools including our Superscript & Subscript Generator use Unicode characters instead of HTML tags.

Unicode includes a specific set of superscript characters commonly used in mathematics, science, and references.

The table below shows commonly supported Unicode superscript and subscript characters used in mathematics, science, engineering, and academic writing. These are the exact characters generated by Unicode-based tools and are compatible across documents, web platforms, and social media.

Character	Superscript	Subscript
0	⁰	₀
1	¹	₁
2	²	₂
3	³	₃
4	⁴	₄
5	⁵	₅
6	⁶	₆
7	⁷	₇
8	⁸	₈
9	⁹	₉
+	⁺	₊
−	⁻	₋
=	⁼	₌
(	⁽	₍
)	⁾	₎
a	NA	ₐ
e	NA	ₑ
h	NA	ₕ
i	ⁱ	NA
k	NA	ₖ
l	NA	ₗ
m	NA	ₘ
n	ⁿ	ₙ
o	NA	ₒ
p	NA	ₚ
s	NA	ₛ
t	NA	ₜ
x	NA	ₓ

Note: “NA” means Unicode does not officially support that character in superscript or subscript form.

Unicode superscript and subscript characters are widely used across multiple disciplines:

• Mathematics: Exponents (x², y³), indices, powers, and equations
• Chemistry: Chemical formulas and compounds (H₂O, CO₂, H₂SO₄)
• Physics & Engineering: Scientific notation (10⁶), variables, equations, and units
• Academic Writing: Footnotes, references, ordinals (1ˢᵗ, 2ⁿᵈ), and annotations

Because these are true Unicode characters, they remain correctly formatted when copied into Google Docs, Microsoft Word, WordPress, PDFs, emails, and social media platforms.

One of the biggest advantages of Unicode superscript and subscript is cross-platform compatibility.

Unicode characters work reliably in:

Because Unicode characters are part of the text itself, they do not depend on formatting rules, fonts, or editors.

This is why text generated using an online Unicode-based superscript and subscript tool remains consistent everywhere.

While Unicode is powerful, it does have limitations.

Key Limitations of Unicode Superscript & Subscript

• Not all letters have superscript or subscript equivalents
• Complex mathematical expressions may not fully convert
• Styling (bold, italics) does not apply separately
• Unicode does not replace full equation editors like LaTeX

For example, Unicode supports superscript numbers well, but not every alphabet character has a superscript or subscript version. This is why some advanced scientific expressions require specialized tools.

A good Unicode generator handles these limitations intelligently by converting only supported characters and leaving the rest unchanged.

Manually typing Unicode superscript and subscript characters is slow, inconsistent, and frustrating. Keyboard shortcuts differ across devices, and built-in character maps are difficult for most users to navigate.
