UnicodeString replace one substring with another

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 "%"

#include <System.SysUtils.hpp>

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

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);
