It'll also help if you present the data in the form of hex byte values. The thing that you say is the "weird character" that whitespace is converted to is not a "character" -- it's a string of up to 14 bytes, two of which are in the ASCII range ("3" and space, which happen to be adjacent in the string: ... 0x33 0x20 ...). I won't hazard a guess as to what the other bytes might represent, because I'm not even sure whether the string you posted is an accurate copy of the output you got. (That's why the hex byte-value dump is important.)

So, your question can't be answered yet, because you haven't shown us what the input looked like or what sort of code is creating the output. And it's not even clear what the output really is.

In case it helps, here's a perl one-liner for generating a simple hex byte dump:

perl -lpe '$_=unpack("H*",$_);s/(..)/$1 /g'

Cyrillic languages use exactly the same whitespace as other languages, no need to convert it to   in html code. So the real question is why are whitespaces in your emails turn to garbage, and you have not provided us with enough information to answer that question. How do you sending these emails?

Probably character encoding mismatch, or MIME encoding mismatch, or both

Without seeing code, I can only speculate. However,   is an HTML encoding of a space, not a Unicode encoding. I *rarely* use Unicode, but I suspect that you're mixing up your symbol sets, missing or extra encode/decode calls, etc. I'd start by making sure you have a Unicode-compatible command window, and start your program in the debugger and look things over as you work your way through the program.

I'd also suggest reading the docs: perlunicode, perlunifaq, perluniintro, and/or perlunitut.

I use this code to send russian emails:

            use MIME::Lite;
            use MIME::Base64;
            
            #MIME::Lite->send( 'smtp', '192.168.0.22', AuthUser => "ki
+njo", AuthPass => "password", Debug => 0 );
            MIME::Lite->send( 'smtp', '192.168.0.22', Debug => 0 );
            
            my $fr_title = encode( 'MIME-Header', $from_title );
            
            my $msg = MIME::Lite->new(
                From    => qq{"$fr_title" <$from_address>},
                To      => qq{<$email_address>},
                Subject => encode( 'MIME-Header', $message_subject ),
                Type    => 'multipart/related',
            );
            
            $msg->attach(
                Type     => 'text/html; charset=UTF-8',
                Data     => $message_html,
            );
            
            my $attachment_name = encode( 'MIME-Header', $attachment_t
+itle . ".doc" );
            #my $attachment_title_temp = $attachment_title;
            
            $msg->attach(
                Type     => 'application/msword',
                Path     => $base_path . '\\' . $dir_name . '\\' . $fi
+le_name . ".doc",
                Filename => $attachment_name,
            );
            
            $msg->attr('content-type.charset' => 'UTF-8');
            $msg->send;

so I was told I had to convert all whitespace to  

That is plain nonsense.   is a non-breaking space, not ordinary white space that is also used with cyrillic text.

it works fine, however whitespace is converted into this weird character: “3 â€

You clearly have an encoding problem. Show us the code sending the e-mail. Also show us the source of a mail that was generated by the code and shows the problem.
