☝🏽 this image is called göögle plus.png - which must be encoded to g%C3%B6%C3%B6gle%20plus.png 

@inherits Custom.Hybrid.Razor14
@using ToSic.Razor.Blade;

@{
  var path = App.Path + "/basics/assets/urls/";
  var exampleImgName = "göögle plus.png";
  var resizeParameters = "?w=100";
  var safeUrl = Tags.SafeUrl(path + exampleImgName + resizeParameters);
}
<img loading="lazy" src='@safeUrl' id="demo-logo">

  ☝🏽 this image is called <code>@exampleImgName</code>
  - which must be encoded to
  <code>@Tags.SafeUrl(exampleImgName)</code>

    width: 50px;

Sometimes you have files with unexpected characters - like umlauts or spaces. The best way to encode this is using Tags.SafeUrl(...) from RazorBlade, or Uri.EscapeUriString(...) from .net.

Important notes

  • Two characters won't resolve properly on a standard web server: + and %. There are ways to work around this, but we would avoid them at all cost.
  • Other characters like spaces, umlauts (öäè) etc. are no problem.
  • You may also find suggestions to use Server.UrlEcode(...). This often doesn't work!
  • Remember to add @@using System to make this fly
