Opera not rendering certain characters from webfonts

问题

Maybe it is not supposed to. But bear with me. I am using Google Web Fonts, and I am including PT Sans font like so:

<link href="https://fonts.googleapis.com/css?family=PT+Sans:regular,italic,bold,bolditalic" rel="stylesheet" type="text/css">

and I even have .htaccess set like so:

<IfModule mod_headers.c>
  <FilesMatch "\.woff$">
    Header set Content-Type "application/octet-stream"
  </FilesMatch>

  <FilesMatch "\.ttf$">
    Header set Content-Type application/octet-stream
  </FilesMatch>
</IfModule>

Now PT Sans font does not include Baltic (ąčęėįšųūž) characters, which I am using. But Chrome, Firefox, IE render them all perfectly - not even using another font. Opera just skips them and leaves an empty space.

Just realized that it only does it with bold fonts. Check this example:

<!doctype html>
<html lang="en" class="no-js">
  <head>
    <title>Font test</title>
    <meta charset="UTF-8">
    <link href="https://fonts.googleapis.com/css?family=PT+Sans:regular,italic,bold,bolditalic" rel="stylesheet" type="text/css">
  </head>

  <body style="font-family:'PT Sans';">
    aceeisuuz<br />
    ąčęėįšųūž
    <p style="font-weight:bold">ąčęėįšųūž</p>
  </body>
</html>

Now how do I fix it?

Looks alright to me, I just threw your example code into a jsfiddle. Maybe there's something else going on with your CSS/page?

Since the PT Sans font does not contain the Baltic characters, browsers will use some fallback fonts. In the absence of declarations for this in the page style sheet, they will use their default methods, so browser differences are to be expected.

It is not clear why Opera sometimes fails here, but it is more important to provide some planned fallback. Either select a completely different font, or at least specify some alternate fonts in your font list, e.g. font-family: 'PT Sans', Arial, sans-serif. This prevents odd mixtures, like PT Sans and Times New Roman (the common default font) and may well circumvent the Opera bug too.
