Introduction

In this section we show how to fix issues with documents that have e-signatures with Asian characters that fail to burn-in.

1. Make sure that the font with Chinese characters (e.g., FangSong) is available on the server (it may need to be installed separately). When using a Windows server, make sure the font is installed for all users.

2. Open the javascript file viewer-assets\js\viewer.js and find this list of fonts used for e-signatures:

   fonts = {
                // Safe serif and sans-serif fonts
                'Times New Roman': { useInLegacy: true },
                'Arial': { useInLegacy: true },
                // Web fonts
                'Cedarville Cursive': { useInLegacy: false },
                'Dancing Script': { useInLegacy: true },
                'La Belle Aurore': { useInLegacy: false },
                'Sacramento': { useInLegacy: true },
                'Pacifico': { useInLegacy: true },
                'Italiano': { useInLegacy: true },
                'Grand Hotel': { useInLegacy: true },
                'Great Vibes': { useInLegacy: true },
   };
   
   

3. Insert the desired font 'FongSang': { useInLegacy: true }

   The location of the font in the list determines the order the e-signature windows displays available fonts. Asian characters may appear indistinct compared to other fonts in the preview, so if desired, unused fonts can be removed from this list so only fonts that support Asian characters are available for e-signatures.

4. Save the file.
