Chromedriver only supports characters in the BMP error while sending Emoji with ChromeDriver Chrome using Selenium Python to Tkinter's label() textbox

It works for me:

from selenium import webdriverJS_ADD_TEXT_TO_INPUT = """  var elm = arguments[0], txt = arguments[1];  elm.value += txt;  elm.dispatchEvent(new Event('change'));  """browser = webdriver.Chrome('C:\\Python37\\chromedriver.exe')browser.get("https://google.com/")elem = browser.find_element_by_name('q')text = "🌎 🌊 " + u'\u2764'browser.execute_script(JS_ADD_TEXT_TO_INPUT, elem, text)

This error message...

selenium.common.exceptions.WebDriverException: Message: unknown error: ChromeDriver only supports characters in the BMP

...implies that the ChromeDriver was unable to send the emoji signal through send_keys() method.

ChromeDriver only supports characters in the BMP is a known issue with Chromium team as ChromeDriver still doesn't support characters with a Unicode after FFFF. Hence it is impossible to send any character beyond FFFF via ChromeDriver. As a result any attempt to send SMP characters (e.g. CJK, Emojis, Symbols, etc) raises the error.

Alternative

A potential alternative would be to use GeckoDriver / Firefox.

• Code Block:

    from selenium import webdriver  from selenium.webdriver.support.ui import WebDriverWait  from selenium.webdriver.common.by import By  from selenium.webdriver.support import expected_conditions as EC  driver = webdriver.Firefox(executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')  driver.get('https://www.google.com/')  # Chineese Character  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.NAME, "q"))).send_keys("𠀀")  # Emoji Character  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.NAME, "q"))).send_keys("💩")

For those who wants to send emojis on Chrome

Solution

    async sendKeysWithEmojis(element, text) {        const script = `var elm = arguments[0],        txt = arguments[1];elm.value += txt;        elm.dispatchEvent(new Event('keydown', {bubbles: true}));        elm.dispatchEvent(new Event('keypress', {bubbles: true}));        elm.dispatchEvent(new Event('input', {bubbles: true}));        elm.dispatchEvent(new Event('keyup', {bubbles: true}));`;        await this.driver.executeScript(script, element, text);    }

Call it like so

const element = await this.driver.findElement(selector);await sendKeysWithEmojis(element, '🚀😀 This one shall pass 🚀😀');

What is happening here?We are emulating native key presses using events

Notice that the {bubbles: true} is optional (Was needed in my case due to a complex wrapped input)
