加载的dxf文件识别不出中文，怎么设置可以识别出文件的中文

[achuan666]

dxf文件已经渲染出来了，但是文件里面的中文以问号线上，请问下怎么设置可以识别中文字符

[ieskudero]

Would be helpful to write the issue in a compatible language :D. Can you share a dxf that I could use to test chinese characters?

This is my model, in Chinese, but when I display it using three-dxf-viewer, some details seem to be missing, as well as garbled characters

modify function _getTextGeometry in src/entites/textEntity to

        _getTextGeometry( entity ) {
		let strings = this._getTextStrings( entity );

		//TODO: if any string's width exceeds entity.refRectangleWidth we must cut it
		let text = strings.join( '' );
		// unicode转中文
		text = text.replace(/\\u\+([\dA-F]{4})/gi, (match, grp) => {
			return String.fromCharCode(parseInt(grp, 16));
		});

		if( Properties.onBeforeTextDraw ) {
			let json = { text: text };
			Properties.onBeforeTextDraw( json );
			text = json.text;
		}

		//get size
		let textSize = this._getTextHeight( entity );

		//generate shape
		let shapes = this._font.generateShapes( text, textSize );
		return new ShapeGeometry( shapes );
	}

and then modify font in src/example/layer/index.js to a Chinese font json. This is one can be used and I have tested.

run npm run dev and enjoy yourself.

By the way, you'd better modify function _getTextHeight in src/entites/textEntity to

    _getTextHeight( entity ) {
		let textSize =  12;
		if ( typeof entity.nominalTextHeight !== 'undefined' )
			textSize = entity.nominalTextHeight;
		else if ( typeof entity.textHeight !== 'undefined' )
			textSize = entity.textHeight;
		textSize =  textSize * 0.8; // downsize the text size to have better layout
		return textSize;
	}
