Replaces all occurrences of a substring within a string, using case-sensitive search.

Use WideReplaceStr to replace all occurrences of the substring AFromText with the string AToText, within the string AText. WideReplaceStr returns the string obtained after replacement.

Use WideReplaceText to do a case-insensitive replacement.

Note: This function is designed for WideString variables. To work with AnsiString variables, use the System.AnsiStrings.StringReplace function. To work with UnicodeString variables, use the System.SysUtils.StringReplace function.

Note: Recursive replacement of substrings is not supported. This means that if the substitution of AToText results in a new match for AFromText, that match is not replaced.

The WideStringReplace function is a more general replacement routine, giving case-sensitivity options, as well as the option to decide whether to replace all occurrences or the first occurrence of the substring in the string.
