UnicodeString replace one substring with another

Question

I can't find a function that will replace one substring with another.

For example, I have a component LabeledEdit and I want to write some text in it. After that, I want to check if there are some spaces in the text and replace them with %.

String text;
text = LabeledEdit1->Text.Trim();
text = text. <- some replace function to replace " " to "%"

[`StringReplace`](http://docwiki.embarcadero.com/Libraries/Rio/en/System.SysUtils.StringReplace)? — Some programmer dude, Sep 20 '19 at 12:20

You can use the RTL's System::Sysutils::StringReplace() function:

Replaces occurrences of a substring within a string.

StringReplace replaces occurrences of the substring specified by OldPattern with the substring specified by NewPattern in the string Source.

#include <System.SysUtils.hpp>

String text;
text = LabeledEdit1->Text.Trim();
text = StringReplace(text, _D(" "), _D("%"), TReplaceFlags() << rfReplaceAll);

with this code

#include <System.SysUtils.hpp>

String text;
text = LabeledEdit1->Text.Trim();
text = StringReplace(text, _D(" "), _D("%"), TReplaceFlags() << rfReplaceAll);

everything working fine

Rather than post your own answer that just quotes the solution that worked for you, it is customary to mark as accepted the answer that gave you the solution. See [What should I do when someone answers my question?](https://stackoverflow.com/help/someone-answers) and [What does it mean when an answer is "accepted"?](https://stackoverflow.com/help/accepted-answer). You have been a member of StackOverflow for over a year and have posted many questions, but you have not accepted any answers given to you so far. – Remy Lebeau Sep 21 '19 at 06:22
