**Hi**

I am trying to create a block for humidity sensor,  
I want the text on it to be: “humidity (%)”,  
But the Makecode keep shows the wrong text…

```auto
namespace mysensor {
	/**
	 * get humidity as a relative percentage value.
	 */
	//% block="humidity (%)"
	export function humidity(): number {
		return sample.humidity;
	}
}

```

**I tried escaping the percentage sign (%) using:**  
“%%”  
“%”  
“\u0025”  
“\uf295” (font awesome % icon)  
 ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/7/75acea3230c976616400fe7d46445ef08b00dd40.png)

But none of this works ☹  
Looking forward for some help,  
Thanks,  
**Arad**

Here’s a block we have with it escaped properly: [https://github.com/microsoft/pxt-common-packages/blob/ee347224faa9135b57017bbf68bf8859c616ed1d/libs/game/mathUtil.ts#L7](https://github.com/microsoft/pxt-common-packages/blob/ee347224faa9135b57017bbf68bf8859c616ed1d/libs/game/mathUtil.ts#L7) (the two slashes should be enough, the bar is just spacing)

**Thanks!**  
Yes the “\%” does the job!
