How to Display Unicode Playing Card Symbols in Your Web Application Without Images?

Understanding the Challenge

You aim to create a font containing Unicode characters from Plane 1, specifically the playing card symbols (U 1F0A0 to U 1F0DF), to display them in your web application without the need for external images.

The Solution: Icomoon App

For this purpose, the Icomoon App offers a convenient solution to create custom fonts. It allows you to:

Creating the Font

  1. Visit the Icomoon App website.
  2. Select the "Upload Custom Icon" option.
  3. Upload a SVG file containing the desired characters, such as the card symbols.
  4. Assign hexadecimal Unicode values (eg. U 1F0A1) to each character.
  5. Download the generated font in a desired format (e.g., WOFF).

Using the Font

To include the custom font in your CSS:

<code class="css">@font-face {
  font-family: 'myfont';
  src: url('fonts/myfont.woff') format('woff');
}</code>
Copy after login

In your HTML, use appropriate classes or CSS selectors to apply the font to the relevant characters:

<code class="html"><span class="card-symbol">?</span></code>
Copy after login

Considerations

  • Avoid using giant fonts: Create a subset font containing only the necessary characters.
  • UTF-8 encoding: Ensure your HTML document uses UTF-8 encoding to display Unicode characters correctly.
  • Browser compatibility: Consider using a fallback font for browsers that do not support @font-face or Unicode Supplementary Multilingual Plane characters.
  • Accessibility: Use alternative text or other techniques for accessibility purposes.
