Especially on large texts UTF-8 can be better, because it needs less memory and fetching memory pages is expensive. I ported the widestring XML units of FPC to UTF-8 because I had to handle thousands of xml files with about 400 MB. Because these documents are in UTF-8 parsing is about 2-3 times faster on these documents, searching is about 20 to 50% faster, which is pretty much the saved memory pages. The UTF-8 overhead is not measurable. Another example are the codetools.
