Unichar not working properly in POWER BI DAX query

[Anonymous]

 am facing an issue with the output of the below DAX query: Health Indicator = SWITCH ( Projects1[Status], "Critical", UNICHAR(128308), "Watch Closely", UNICHAR(128993), "On track", UNICHAR(128994))

In the report only for Critical status health indicator is showing red circle. For others, it is showing a blank square. 

I tried the workaround query provided them as below but no luck: Health Indicator = SWITCH ( Projects1[Status], "Critical", UNICHAR(128308) & " ", "Watch Closely", UNICHAR(128993) & " ", "On track", UNICHAR(128994) & " ")

Can someone please point out the the issue here?

Thanks!

@Anonymous , Created a measure like this and it is working

Measure 7 = SWITCH ( max('Item'[Category]), "Category 1", UNICHAR(128308) , "Category 2", UNICHAR(128993) , "On track", UNICHAR(128994) )

Try like

Health Indicator = SWITCH ( max(Projects1[Status]), "Critical", UNICHAR(128308), "Watch Closely", UNICHAR(128993), "On track", UNICHAR(128994))
