In some text fields in Chrome, I can't edit between two consecutive lowercase letter F's. For instance, on the search box for Logz.io this happens and on my company's backend which uses bootstrap 3.

So far I haven't been able to figure out what the commonality is. I had a colleague confirm it happens on his computer as well. This seems to be a really strange bug. What could be the cause of it?

  • Works fine for me (on the given site). What language settings do you use? In some languages, ff could be a special char, like ‘ll’ or ‘rr’ in spanish [those are single characters in spanish] – Aganju Feb 8 '18 at 2:40
  • I'm using US English. My colleague is using the same. Both of us on MacOS Sierra and Chrome 63.0.3239.132. Maybe we both have some Chrome extension in common that's doing it. – EcomEvo Feb 8 '18 at 3:13

    Check something isn't replacing the 2 f's ff with a ligature, ff - they may look the same but they are different characters; the ligature is a single character. Copy/paste your double f & my ligature into the Keyboard,Emoji, Symbol viewer to test [system prefs/keyboard/keyboard to enable it in the menu bar] – Tetsujin Feb 8 '18 at 7:34

What could be the cause of it?

It could be an ff ligature such as Unicode Character 'LATIN SMALL LIGATURE FF' (U+FB00)

It is conceivable that a typed ff is replaced with ff by an autocorrect feature or smart-typography feature.

Typography selection dialog


/* Enable Ligatures ================ */
letter-spacing: 0;
-webkit-font-feature-settings: "liga";
-moz-font-feature-settings: "liga=1";
-moz-font-feature-settings: "liga";
-ms-font-feature-settings: "liga" 1;
-o-font-feature-settings: "liga";
font-feature-settings: "liga";
  • The moment I copy it out of the field in question where it appears to be a ligature FF, and paste into the characters search field on my Mac, it turns into a regular double f. – EcomEvo Feb 8 '18 at 15:57
