hi every body.
1- i solve this by puting my font file into public/fonts folder
2- edit this line in my them variables.less:

//** Load fonts from this directory.
@icon-font-path: "fonts/";
//** File name for all font files.
@icon-font-name: "Samim";
//** Element ID within SVG icon file.
@icon-font-svg-id: "Samim";

3- change font-family to "Samim"
