</code></pre>

<p>Read char from stdin, jump to 0x7d if EOF.</p>

<p>Sidenote: This actually is a small (but pretty well known) trick, 0x7d contains <code>ret</code>,
this will cause <code>pop sp</code>, <code>sp</code> at start points to end of a segment, there's <code>00 00</code> there, and <code>cs:0</code> in DOS contains <code>CD 20</code>, which causes application to exit.</p>

<pre><code>0055 8a05               mov         al, [di]   
0057 3c80               cmp         al, 0x80

005e ebec               jmp         0x4c       
</code></pre>

<p>If char is &lt; 0x80, just print it out, and go to beginning of loop
(because helper function is setting BX to 1 - stdout, jumps will go to <code>dec bx</code>)</p>

<pre><code>0060 3ca0               cmp         al, 0xa0   
0062 721a               jc          0x7e

0069 50                 push        ax         
006a 86c4               xchg        ah, al

0073 ebd7               jmp         0x4c       
</code></pre>

<p>This part deals with chars >= 0xa0, splits ascii code into "high" two bits and "low" 6 bits and applies utf-8 mask c080 for two bytes, then prints both of them</p>

<pre><code>007e 2c80               sub         al, 0x80   
0080 d0e0               shl         al, 0x1

0097 ebcd               jmp         0x66       
</code></pre>

<p>This part deals with chars >= 0x80 &lt; 0xa0, it finds proper utf-8 code in the table at the top, if code equals 0, just skip to beginning, if it's below 0x7ff (ergo: fits on two UTF-8 bytes), just adjust the value and re-use previous code at 0x166.</p>

<pre><code>0099 50                 push        ax         
009a c1e80c             shr         ax, 0xc    
009d 0ce0               or          al, e0     
009f e8d3ff             call        0x75       
00a2 58                 pop         ax         
00a3 25ff0f             and         ax, 0fff   
00a6 c1c002             rol         ax, 0x2    
00a9 c0e802             shr         al, 0x2    
00ac 0d8080             or          ax, 8080   
00af 50                 push        ax         
00b0 86c4               xchg        ah, al     
00b2 ebb8               jmp         0x6c       
</code></pre>

<p>Final part, deals with codes that are above 0x7FF, drop low 12 bits,
apply 0xE0 (see <a href="https://en.wikipedia.org/wiki/UTF-8#Description" rel="nofollow noreferrer">UTF-8 encoding description</a> for reference) and print it out,
adjust lower 12 bits and apply 8080 mask and again reuse part that spits out two chars.</p>

<h1>Scala 3, 18 bytes</h1>

<p><a href="https://scastie.scala-lang.org/gGDVsWJ4RICsWZt8LY1QuQ" rel="nofollow noreferrer">Try it in Scastie!</a></p>
<p>Ordinarily, I wouldn't post such a trivial answer, but this demonstrates Scala 3's universal apply methods, which let you omit <code>new</code>.</p>


<p>Given a string, character list, byte stream, sequence… which is both valid UTF-8 and valid Windows-1252 (most languages will probably want to take a normal UTF-8 string), <a href="https://en.wikipedia.org/wiki/Mojibake" rel="noreferrer" title="Mojibake - Wikipedia">convert it</a> from (that is, <em>pretend</em> it is) <a href="https://en.wikipedia.org/wiki/Windows-1252" rel="noreferrer" title="Windows-1252 - Wikipedia">Windows-1252</a> to <a href="https://en.wikipedia.org/wiki/UTF-8" rel="noreferrer" title="UTF-8 - Wikipedia">UTF-8</a>.</p>
<h3>Walked-through example</h3>
<p>The UTF-8 string<br />
<code>I</code>  <code> </code>     <code>♥</code>     <code> </code>  <code>U</code>  <code>T</code>  <code>F</code>  <code>-</code>  <code>8</code><br />
is represented as the bytes<br />
<code>49</code> <code>20</code>  <code>E2 99 A5</code>  <code>20</code> <code>55</code> <code>54</code> <code>46</code> <code>2D</code> <code>38</code><br />
these byte values in <a href="https://en.wikipedia.org/wiki/Windows-1252#Character_set" rel="noreferrer">the Windows-1252 table</a> gives us the Unicode equivalents<br />
<code>49</code> <code>20</code> <code>E2 2122 A5</code> <code>20</code> <code>55</code> <code>54</code> <code>46</code> <code>2D</code> <code>38</code><br />
which render as<br />
<code>I</code>  <code> </code>  <code>â</code>  <code>™</code>  <code>¥</code>  <code> </code>  <code>U</code>  <code>T</code>  <code>F</code>  <code>-</code>  <code>8</code></p>
<h3>Examples</h3>
<p><code>£</code> → <code>Â£</code></p>
<p><code>Â£</code> → <code>Ã‚Â£</code></p>
<p><code>Ã‚Â£</code> → <code>Ãƒâ€šÃ‚Â£</code></p>
<p><code>I ♥ UTF-8</code> → <code>I â™¥ UTF-8</code></p>
<p><code>árvíztűrő tükörfúrógép</code> → <code>Ã¡rvÃztÅ±rÅ‘ tÃ¼kÃ¶rfÃºrÃ³gÃ©p</code></p>
