In case the application requires text information that changes in real-time (e.g. location names while driving) the rendering has to be done on the fly. For this Unity gives an option to use Dynamic Text in font import settings. The Dynamic Text uses the Freetype font rendering engine to create font texture in real-time and reduces the file size of the application by using system fonts, thereby replacing the need for font embedding. Content developers use this quite often when they require support for Asian languages or large font sizes that generate massive file sizes to accommodate font textures. However, Dynamic Text allows embedding of font data using the “Include font data” option. When the font data is not included, and the font is not available in users’ systems, then Unity replaces the font based on a hard-coded global list of fallback fonts that are generally installed on the platform it is being used on.
