Problem with displaying Cyrillic characters in the BPMN scheme

[kucher-racer]

There is a problem with displaying Cyrillic characters in the BPMN scheme

this happens when decoding base64 via the atob function, please add another decoding function

worked example:
const xml = decodeBase64ToUtf8(props.diagramData);

function decodeBase64ToUtf8(base64) {
// decode base64 in binary data
const binaryString = atob(base64);

// Convert array byte
const binaryLen = binaryString.length;
const bytes = new Uint8Array(binaryLen);
for (let i = 0; i < binaryLen; i++) {
bytes[i] = binaryString.charCodeAt(i);
}

// Decode bytes as UTF-8
const decoder = new TextDecoder('utf-8');
return decoder.decode(bytes);
}
