Square root symbol is not displayed correctly

[edSantiago01]

When displaying the square root character on the screen, the symbol is displayed divided into 2 parts (the character on the left side and a line above the elements, these two elements are not joined).

For Example (Kotlin on Android Studio 4.1.3):
mvTest.apply { text = "$$ c = √{a^2 + b ^2 } $$" }
