The trademark symbol looks small on the main font, so we need to apply a different font for that character using @font-face{ unicode-range }. We got the trademark symbol correct, but the overline and the line-spacing are affected.

@font-face {
  font-family: ARNO;
  src: local("ArnoPro-Subhead");
}
@font-face {
  font-family: STIX;
  unicode-range: U+AE-AE;
  src: local("STIXGeneral");
}
body {
  font-size: 11pt;
  line-height: 1.2;
  text-align: justify;
  text-justify: inter-word;
  hyphens: manual;
}
.arno{
  font-family: ARNO;
}
.stix{
  font-family: STIX, ARNO;
}
.overline{
  text-decoration: overline;
}

<div class="arno">we get correct overline and line-spacing</div>
<div class="stix">But for stix font the overline and line-spacing changed.</div>

I've created a sample demo file to demonstrate the issue, kindly let me know if there is any workaround?

We will investigate this issue, perhaps in the meantime you can set an explicit line-height?

Currently line-height is coming from body and no other tag have line-height property

body {
    line-height: 1.2;
}

If we use hard-coded values (like 13pt), then I've to give it for all style elements (like h1, h2, h3). Also, it doesn't solve the overline moving further up.

May I know, if you have already investigated this issue?

Another idea worth trying would be to specify Arno first instead of second, but restrict it to apply to every Unicode character except U+AE.

So, you're suggesting like

{
  unicode-range: U+AE;
  font-family: STIX;
}
{
   unicode-range: U+00-AD, U+AF-FF;
   font: ARNO
}
and define ARNO first like:
font-family: ARNO, STIX

but we're dealing with many unicode, kindly look into the attachment and defining all non STIX ranges in main font is not so easy

True, that looks complicated! But you only need to exclude the specific characters you don't want to use from Arno, right? Characters that Arno doesn't have will still fall through to STIX.

(The unicode-range will need to go to FFFF though, not just FF).

Yes, its complex.

But the ranges which we want to go with STIX is also available in ARNO too, so for your suggestion we have to create a exclude range for ARNO (removing all STIX range) also this way will be complex for maintenance too - im worried here

It might be easier to just wrap the TM character in a span and apply a different font-family!

yeah, but still the span touches the line-height. I think i've to wrap display:inline; and play with line-height...

After all, it would be good if you guys fix this in the Prince rather patchy works

You could apply "line-height: 0" to the span so it does not affect the containing line at all. But we will take a look at what is going on.

ok, thank you for your support Mike
