Check whether two strs have at least one shared character.

Hello,

Is there a simple way/command/function to check whether two strings have 
at least one overlap character please?

For example,

str1: 05baaa
str2: ooboo

Query: select str1 ??? str2 ;

Result: true

Because b is in both str1 and str2.

Thank you!

SELECT str1 ~ ( '[' || str2 || ']');
