In my website, posts occasionally contain characters from a second language (Urdu), which the google web-font set by my theme, of course does not recognize and resorts to a fallback font. I was wondering if there might be a way to override the fallback font for unrecognized characters to one of my liking(that supports Arabic/Urdu script) such as the google early access Noto fonts which include arabic and urdu fonts. Would this work as I understand it should? will any characters in Arabic/Urdu script be rendered with the specified font by doing so? I would love to know how one could implement/ enqueue necessary files in a WordPress theme. Any thoughts would be greatly appreciated.

Thanking you very much for your time, Sameer

excerpt from post with arabic characters:

ALL MEMBERS, السلام عليكم With the arrival of summer, the Swimming Pool & Gymnasium activities shall commence from Saturday the 1st of APRIL 2017.

I think the only solution is unicode-range in your @font-face (https://developer.mozilla.org/en-US/docs/Web/CSS/@font-face/unicode-range). Unfortunately you've to note every single character (or a range) you would like to display via the font in your basic @font-face.

After that you can enqueue another webfont with the missing chars and make it available:

font-family: 'font without arabic chars', 'font with arabic chars', sans-serif

Of course there are a few browser issues in older browsers: http://caniuse.com/#search=unicode-range

  • I was wondering what is the reason for the @ font-face rule and unicode range, I followed your instructions by enqueueing the arabic font in the themes functions.php, and simply addding the css .entry-content{font-family:Noto Sans, cairo !important;} (cairo is the arabic font) This seems to be working without specifying unicode characters. wherever there are arabic/urdu characters are being rendered with the cairo font. I was wondering what are the advantages of using the @ font-face rule. – Sameer Ali Apr 24 '17 at 14:25
  • you’re totally right. of course you can do it without unicode-range. you can use unicode-range in case you want exclude parts or single chars of each font which you load via @font-face. Especially in your case – when you want to exclude the arabic range from Noto Sans and fallback to cairo you can do it with unicode-range. Noto should include a comprehensive range of languages as you can see in their project website: google.com/get/noto you need to make your webfonts available in your stylesheet via @font-face like in this example jsfiddle.net/h906qu6v – s t Apr 25 '17 at 17:41
  • so by setting a unicode range only the characters I specify will use the fallback font? so does this mean that the entire font is not downloaded to the client machine and only the characters specified ? does enqueueing a font download the entire font regardless whether it is used or not? I guess my question is does this technique save bandwidth/page load time in any way? – Sameer Ali Apr 26 '17 at 10:40
