You can override default angular encoding with adding Interceptor which fixes this:

import { HttpInterceptor, HttpRequest, HttpEvent, HttpHandler, HttpParams, HttpParameterCodec } from "@angular/common/http";
import { Injectable } from "@angular/core";
import { Observable } from "rxjs";

@Injectable()
export class EncodeHttpParamsInterceptor implements HttpInterceptor {
  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const params = new HttpParams({encoder: new CustomEncoder(), fromString: req.params.toString()});
    return next.handle(req.clone({params}));
  }
}


class CustomEncoder implements HttpParameterCodec {
  encodeKey(key: string): string {
    return encodeURIComponent(key);
  }

  encodeValue(value: string): string {
    return encodeURIComponent(value);
  }

  decodeKey(key: string): string {
    return decodeURIComponent(key);
  }

  decodeValue(value: string): string {
    return decodeURIComponent(value);
  }
}

and declare it in providers section of in app.module.ts

providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: EncodeHttpParamsInterceptor,
      multi: true
    }
]
