request don't support characters as : " í ", " ë ", " å " ..

Summary

Hello, it's been few days that am struggling with a problem. Am trying to fetch the information about a city with [openweathermap api](https://openweathermap.org/current. A normal request looks like this e.g:
http://api.openweathermap.org/data/2.5/weather?q=CITY&units=metric&appid=APIKEY

(you can reproduce this in your browser with a free api key)

result: (JSON)
{"coord":{"lon":-73.61,"lat":45.5},"weather":[{"id":802,"main":"Clouds","description":"scattered clouds","icon":"03d"}],"base":"stations","main":{"temp":24.65,"pressure":1012,"humidity":38,"temp_min":24,"temp_max":25},"visibility":48279,"wind":{"speed":7.2,"deg":280,"gust":11.3},"clouds":{"all":40},"dt":1535058000,"sys":{"type":1,"id":3829,"message":0.0049,"country":"CA","sunrise":1535018756,"sunset":1535068008},"id":6077243,"name":"Montreal","cod":200}

I use this function made with request module:

``

function req (url, jsonStatus){
    const options = {
        uri: url,
        json: jsonStatus 
    }

    console.log(`Sent: ${options.uri}`)

    rp(options)
        .then(repos => {
            console.log(`Success: ${repos.sys.country}`) // Country code is returned
        })
        .catch(err => {
            console.log(`Error: ${err}`)
        })
}}
const owmUrl = `http://api.openweathermap.org/data/2.5/weather?q=${City}&units=metric&appid=${apiKey}`;
req(owmUrl, true);

Outpout(console)(where city is 'montreal'):
`λ node app
Sent: http://api.openweathermap.org/data/2.5/weather?q=montreal&units=metric&appid=APIKEY

Success: CA`

As you see here, the request is a success. When trying with cities with special characters as "Chamberí " from the browser, everything goes fine, the url looks like this:
http://api.openweathermap.org/data/2.5/weather?q=Chamberí&units=metric&appid=APIKEY

and result is (JSON again):
{"coord":{"lon":-3.71,"lat":40.44},"weather":[{"id":800,"main":"Clear","description":"clear sky","icon":"01n"}],"base":"stations","main":{"temp":27.24,"pressure":1020,"humidity":32,"temp_min":27,"temp_max":28},"visibility":10000,"wind":{"speed":3.6,"deg":110},"clouds":{"all":0},"dt":1535059800,"sys":{"type":1,"id":5488,"message":0.0039,"country":"ES","sunrise":1535002448,"sunset":1535050778},"id":3117735,"name":"Chamberí","cod":200}

but if I send this with the code I made, I end up with this :

λ node app Test Sent: http://api.openweathermap.org/data/2.5/weather?q=Chamberí&units=metric&appid=0ec25df3f69726843a58a325b97e845d Error: StatusCodeError: 404 - {"cod":"404","message":"city not found"}

I don't understand why I get this error since trying the same url in my browser works perfectly. I tried using the modules request-promise and request-promise-any but both of them return the same error.

The is something wrong this and I don't know if it's me of the module. If I could get help, it will be very appreciated :)

Thank.

(am sorry if something wrong with my issue request, it's the first time that I do this :) )
