Shiny Web Application Framework For R For the sake of consistency and portability, shiny requires the character encoding of all its components to be utf 8, which include ui.r, server.r, global.r, description, and or readme.md. note a shiny app may not contain all of these files, but all of them must be encoded in utf 8 if they exist. Solution was very simple just add "lc all=en us.utf 8" to etc default locale. best regards! i have had this issue for a while. i was working around by not using special characters. however it's high time to solve it. issue is very simple: perfectly working app on local run stops working w.
Screenshot Of The Web Page With Text And Numbers In Blue Red Yellow Because "\xe9" doesn't represent é in the default encoding in linux, calling enc2utf8() won't convert it to a é encoded in utf 8. the most straightforward solution is to use the unicode escape code instead: "\u00e9". Learn how to resolve the `input string 1 is invalid utf 8` error in your shiny app. this blog provides a step by step approach to ensure your app runs smooth. In your case i would suggest producing a shinyapp with little more than the auto shiny template that studio gives for make a new shiny app, declare a string with examples of utf 8 characters and directly try to render them in a shiny output. Although we recommend utf 8 in shiny, it is not the default encoding on windows anyway, so your app users may have trouble especially when they have file interactions with your app.

When i containerize the app with docker, the display looks the same as it does on shinyapps.io (square icons instead of the correct icons) if i import from rocker shiny, and it doesn't display any icons at all if i import from rocker shiny verse. Before this error, the app has been running with no problem and nothing has been changed in the code. i have tried all i can to get to the root of the problem but to no avail. any idea pointers to what could be causing this? i suspect this to be causing the error. When dealing with encoding problems, you are not recommended to set the encoding option to a specific encoding name, e.g. options (encoding = 'utf 8'). this may have very bad consequences, since it makes a strong assumption that all file connections and character manipulations should use this encoding by default.
