English: A image showing a bug in librsvg, the software used by Wikimedia wikis to render SVG files. It shows four lines of text, each having a different font-family property. As per , the first line should look the same as the second and the third, as they all have the Courier font set. Courier is supported by librsvg. However, the difference is that in the second and third lines, the Courier font has the highest priority (first on the list) while in the first line, the priority of Courier is second to Courier New, an unsupported font. Librsvg considers only the highest priority font when multiple fonts are specified in font-family, if it is not installed on the rendering servers it renders text with its default or replacement font even if there are lower-priority fonts that are supported
