Steps to reproduce



There’s a bug in Edge concerning one of the features of the CSS3: automatic hyphenation. Edge hyphenates words only if the language of the webpage is the same as the language version of the underlying OS. This is highly impractical in modern world: many users browse pages in more than one language. Hyphenation rules should be built-in the Edge to display properly any webpage, regardless of the Windows language version. As far as I’m concerned, that’s the way Firefox handles this issue – by having hyphenation rules for all languages built-in. I attached a screenshot illustrating the issue.

To reproduce a bug, we’ll simply create a simple index.html document…

<!DOCTYPE html>
<html lang="en-US">
<meta charset="UTF-8"> 
<link rel="stylesheet" href="styles.css">
<p>Sample long text in English[…]<\p>

…with the following CSS sheet called styles.css:

p {
-webkit-hyphens: auto;
-moz-hyphens: auto;
-ms-hyphens: auto;
hyphens: auto;
text-align: justify;

If the language installed in your Windows is the same as the language declared in the index.html, then you get to see the formatting. However, if you decide to put some French text as a sample and change the language to <html lang="fr"> then the hyphenation is gone.

tl;dr Edge provides fancy CSS hyphens only for one language (i.e. the one you use in Windows)
