XML enconding problem

[anonymous_user_f7c0f7221 (anonymous_user_f7c0f722)]

Hello,

I created, in c++, functions based on the XML libraries from Epic.

When a file is read, the characters on the blueprint debug show as having encoding problems.

I included in the XML the header :

<?xml version="1.0" encoding="utf-8" ?>

but it doesn’t work.

Do I need to add something?

bool UDatabaseManager::readXML(FString fileName)
{
	if (currentFile != nullptr) {
		//saveXML();
	}
	FString path = FPaths::GameDir() + FString("Content/A_RTS/UnitInfo/") + fileName + ".xml";
	
	filePath = path;
	
	currentFile = new FXmlFile(*path);
	if (currentFile->IsValid()) {
		fileLoaded = true;
		return true;
	}
	fileLoaded = false;
	return false;
}

bool UDatabaseManager::saveXML()
{
	if (fileLoaded) {
		return currentFile->Save(*filePath);
	}
	return false;
}

bool UDatabaseManager::addChildNode(FString parent, FString newTag, FString newValue)
{
	if (fileLoaded) {
		FXmlNode* root = currentFile->GetRootNode();
		root->FindChildNode(parent)->AppendChildNode(newTag, newValue);
		return true;
	}
	return false;
}

		TArray<FXmlNode*> parentsChildren = parentNode->GetChildrenNodes();
		FXmlNode* toRemove = parentNode->FindChildNode(tagToRemove);
		if (toRemove != nullptr) {
			parentsChildren.Remove(toRemove);

Can anyone help me?
