Indeed, observe two occurences of `фѕф`; in the first one, the letters are separated by combining characters; in the second,\r\nthere is no intervention.  Likewise, 2 final letters of final `ффф` are separated by 2 combining characters.\r\n\r\nThe font is a monospaced font, in which `x` and `dx` are changed via a `mark` feature (by `-512`).  The font works fine on Window in a `GDI` applications (`notepad` and `Character Map`); in `Uniscribe` applications (I checked `WordPad`) there is a small *positive* kern inserted.\r\n\r\n(I plan to update the font to `v10.0.0.7`; after this I would provide a link to download the font.  Or, if urgent, let me know, and I would provide a current, obsolete, version.)\r\n\r\n- [x] Screenshot\r\n- [x] The FontForge version and the operating system you're using\r\n- [x] The behavior you expect to see, and the actual behavior\r\n- [x] Steps to reproduce the behavior \r\n- [ ] \\(optional) Possible solution/fix/workaround"},"comment":{"url":"https://api.github.com/repos/fontforge/fontforge/issues/comments/373287139","html_url":"https://github.com/fontforge/fontforge/issues/3267#issuecomment-373287139","issue_url":"https://api.github.com/repos/fontforge/fontforge/issues/3267","id":373287139,"user":{"login":"ilyaza","id":4063329,"avatar_url":"https://avatars3.githubusercontent.com/u/4063329?v=4","gravatar_id":"","url":"https://api.github.com/users/ilyaza","html_url":"https://github.com/ilyaza","followers_url":"https://api.github.com/users/ilyaza/followers","following_url":"https://api.github.com/users/ilyaza/following{/other_user}","gists_url":"https://api.github.com/users/ilyaza/gists{/gist_id}","starred_url":"https://api.github.com/users/ilyaza/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ilyaza/subscriptions","organizations_url":"https://api.github.com/users/ilyaza/orgs","repos_url":"https://api.github.com/users/ilyaza/repos","events_url":"https://api.github.com/users/ilyaza/events{/privacy}","received_events_url":"https://api.github.com/users/ilyaza/received_events","type":"User","site_admin":false},"created_at":"2018-03-15T07:36:34Z","updated_at":"2018-03-15T07:36:34Z","author_association":"NONE","body":"Now the font is available at\r\n http://ilyaz.org/software/fonts/unifont-smooth-mono-10.0.07--1.230-no-Han-Hangul.7z\r\n."}}
