What compatibility issue may arise concerning text displayed on the World Wide Web?

The compatibility issue related to text displayed on the World Wide Web primarily revolves around web safe fonts and font replacements. Web safe fonts are standard fonts that are universally available across different systems and browsers. Issues arise when web designers use non-standard fonts that may not be installed on all users' devices, leading to variations in how text is displayed.

If a specified font is not available, browsers generally substitute it with a default font, which can alter the intended design, layout, and overall user experience. This is particularly critical in multimedia applications where consistent visual branding and readability are important. Choosing the right fonts and implementing proper fallbacks is essential for ensuring that text maintains its integrity across various platforms and devices.

In contrast, compatibility issues related to images, type restrictions, or the need for third-party applications do not directly address the common concerns of font display and its impact on text visibility and aesthetics on the web.
