 ''%%""%%'' is an empty string, i.e. a valid string of length 0. It can be passed to any function and will work as expected. ''%%""%%'' is an empty string, i.e. a valid string of length 0. It can be passed to any function and will work as expected.

 Operator ''=='' only checks if string **numbers** are equal. It may mostly work and then stop working randomly, or when used with a string coming from a different ACS library. Operator ''=='' only checks if string **numbers** are equal.

-To check if strings are equal, you need to compare their contents. ACSUtils provides an easy to use function to check if strings are equal:+To check if strings are equal, you need to compare their contents. ACSUtils provides an easy to use function for this, which returns true if two strings are equal:
  
 ''bool StrEquals(str a, str b)'' ''bool StrEquals(str a, str b)''
  
-And also a case-insensitive version:+Internally, this function calls harder to use [[zdoom>StrCmp]], but it could just as well be implemented using a combination of [[zdoom>StrLen]] and [[zdoom>GetChar]].

 ''bool StrIEquals(str a, str b)'' ''bool StrIEquals(str a, str b)''
