This page does not work any more, even on IE, since the technology used has been removed. The Wordmark.it page lets you see a string with fonts on your computer; it says it uses ”the new Local Font Access functionality currently supported by Google Chrome and Microsoft Edge browsers.” However, it seems that on Android, it only show a small set (like 16) ”system fonts”.
The following is the old content and now obsolete:
This page shows a given text in all fonts installed in the user’s system. The page works in Internet Explorer only and requires that script execution is allowed.
Alternative tools:
The Last Resort font (if installed) is used as the secondary font to reveal situations where some font does not contain the characters in the test string.
