Mailto Apostrophe无法正确显示

Question

Fiddle

当尝试通过表单使用HTML mailto时，我输入了诸如let，w或诸如此类的带有撇号的单词，它显示为t’ 而不是

<form action="mailto:name@example.com?subject=Website Feedback" method="post" enctype="text/plain">
Email Adress:<br />
<input value="Let’s It’s " type="text" name="email_address" value="" maxlength="100" /><br />

Comments:<br />
<textarea  rows="5" cols="20" name="comments"></textarea><br />

<input type="submit" value="Submit" />

</form>
