Well, there is a lot of UTF8 strings that do not pass your checks ;)
If you remove low ascii control chars
Hi, JoshyFun
Thanks for pointing out the bug in my coding, yes you are right. I forgot to
put some checking before every inc(i,k) and continue; there should a
judgement statement
*if ilength(UnknownStr) then exit(false);*

You combine a IsText (no special characters in #0-#31) and IsUTF8 - good
idea.
function IsUTF8(UnknownStr:string):boolean;
Maybe
Not every ansi string is a valid UTF8 string, but every UTF8 string is a
valid ansi string. So you can be sure that a string is not a valid UTF8
string, if it's a valid, it could be a UTF8 or an ansi string.
You can make some guess, for latin alphabet (western or eastern), if it
is a valid UTF8

In general: No, because every 8bit combination is valid.
In specific case: Not every combination makes sense. So you can write
heuristics.

I refer to a text loaded in a SynEdit by the user in which I need to
make some string manipulations.

Distinguish UTF-8 from what?
ANSI, UTF16 or whatever?

You can not determine if a string is an UTF8 one, only if it is an
UTF8 well formed sequence. In other words, you can not detect if a
string IS an UTF8, only if it does not have UTF8
