Selenium Java automation with Browserstack automate, when trying to test with international languages like Korean it converts the character on BS

Question

When we try and enter below text on web via browserstack it converts the characters:

"chineseSampleQuery": "我想为我的儿子购买平板电脑",
"koreanSampleQuery": "아들을 위해 태블릿을 사고 싶어요",
"arabicSampleQuery": "أريد أن أشتري لوحاً لابني",

E.g: when entered "Ä ä Ö ö Ü ü ẞ ß" it converts as "Ä ä Ö ö Ãœ ü ẞ ß" while entering to input filed. I've tried 2 ways:

any suggestion how to achieve this? Screenshot of how it's converted'Ä ä Ö ö Ü ü ẞ ß'(https://i.stack.imgur.com/UBUb7.png)

1.

String text = "이 사이트에서 태블릿을 구입할 수 있습니까?";
byte[] utf8Bytes = text.getBytes("UTF-8"); // Replace with the appropriate encoding

driver.findElement(By.id("yourInputField")).sendKeys(new String(utf8Bytes, "UTF-8"));

String koreanText = "\uC774 \uC0AC\uC774\uD2B8\uC5D0\uC11C \uD0C0\uC785\uB9CC \uAD6C\uC785\uD558\uC9C0 \uC54A\uC2B5\uB2C8\uB2E4?";

Both did not work.
