+While working on my custom [Anki] cards for learning Japanese and Turkish, I
+found that my font of choice for Japanese [IPAex] was not properly supporting
+glyphs used by Turkish, like [ğ].
+
+To fix this i am using a property of the `@font-face` rule to limit custom
+fonts to source their glyphs from a subset of the unicode range and force
+fallback to the next font in the set.
+
+```css
+@font-face {
+    font-family: "IPAexGothic";
+    src:
+        local("IPAexGothic"),
+        url("_ipaexg.ttf");
+    unicode-range: 
+        U+0020-007F,
+        U+3000-303f,
+        U+3040-309f,
+        U+30a0-30ff,
+        U+ff00-ffef,
+        U+4e00-9faf;
+}
+
+.card {
+    font-family:
+        IPAexGothic,
+        Noto Sans,
+        sans;
+}
+```
