removeSpecialCharacters()

Removes the trademark or other special characters to make comparisons easier.
The function is in the /lib/common.vbs file.
Purpose

registered symbols with "".
Syntax
removeSpecialCharacters(s)
Input parameters
String s
Return values
String s

versionCompare()

Parses the input parameters that represent the actual and expected values for a
prerequisite property and compares them to determine whether the prerequisite
property passes the prerequisite check. The function expects dot-separated version
strings as input parameters, for example, 1.0.0.4, 2.3, 3.40.26.7800 or 2.3.*.
Purpose
This function first handles special cases where either one or both input parameters
are empty and returns return codes to represent these cases. It splits each version
into several parts by the dot separator. If the last part of the version is the *
wildcard character, the function considers all missing parts of the version to be the
wildcard character, for example, 2.* matches 2.1 or 2.3.*. It then loops through the
list of parts for each version and compares them. It then returns return codes
depending upon whether the expected value is less than, equal to, or greater than
the real value.
