How Can I Prevent Emojis from Rendering When Using Special Characters in Web Content?

Encoding Special Characters: Preventing Emoji Rendering

When incorporating special characters into web content, it's essential to control their visual representation. Some Unicode characters can be displayed as either classic glyphs or modern emojis, which may not align with your desired design. To prevent this rendering inconsistency and ensure consistent presentation, a solution is needed.

One approach to this problem is utilizing Unicode Variation Selectors. These selectors provide control over the way a character is displayed. By appending the Unicode Variation Selector character for forcing text (︎) to a Unicode character, you can force the rendering of the text version of the character, preventing it from appearing as an emoji.

For instance, the hourglass character can be rendered as either an emoji (⌛) or a glyph (⌛). To ensure that it is displayed as a glyph, you can append the Unicode Variation Selector character as follows:

⌛︎

This will force the hourglass character to appear as a monotone glyph instead of an emoji, regardless of the browser used.

It's important to note that not all browsers fully support Unicode Variation Selectors. Some browsers, such as Chrome and Edge, may not honor this setting. As a result, it's recommended to use alternative methods for cross-browser compatibility.
