Devicon CSS versioning and glyph mapping mismatch

Integrating Devicon into a web application involves linking a CSS stylesheet that maps specific class names, such as devicon-javascript, to unicode characters within a web-font file. When updating the library version or switching from a CDN to local hosting, the alignment between the CSS mapping and the font binary must be exact.

A potential conflict arises when the CSS file is updated to a newer version while the browser continues to cache an older version of the .woff or .ttf font files, or vice versa. Because these icons are rendered as pseudo-elements, a mismatch in the unicode mapping can result in the display of incorrect glyphs or empty squares.

What is the recommended strategy for ensuring atomic updates of both the CSS and font assets to prevent rendering artifacts? Is there a documented way to verify unicode compatibility between two specific Devicon releases without manual CSS inspection?
