Why Am I Seeing Yellow Highlighting on My Text?

Much of the stuff I do requires headlines or subheads IN ALL CAPS. I make a paragraph style using the Case: All Caps setting in the Paragraph Style Dialog box. This will make the text all-caps but then mark each word in yellow highlighting as if it were a substituted glyph issue!

It has been a while since we tackled the dreaded highlighting “problem.” I put the word in quotes because it turns out it’s usually not a problem at all, but it can certainly freak you out if you don’t know what’s going on.

Every so often, you’ll find documents in which text is highlighted in a dark yellow — not all the text, but a little bit here and a little bit there. Usually all the “fi” and “fl” ligatures are highlighted; sometimes whole words that are in all caps or small caps. The reason: Substituted Glpyhs is turned on the Composition pane of the Preferences dialog box:

Yellow Highlighting Substituted Glyphs

Substituted glyphs means any character in the text which is being substituted for something else; so you’ll always get it with ligatures and formatting in which a lower case character is swapped out for a capital or small cap.

This is a document preference rather than an application preference; that is, if you turn it on when a document is open, just that one document remembers the change. But it also means that you can open a document from someone else and see it (because they turned it on). Here’s an example:

YellowHighlight2

So should you panic? Rebuild your preferences? Reinstall the entire Creative Suite? Buy a new computer? Sure! Though of course none of those things will make the yellow go away. Instead, I suggest you just turn off the Substituted Glyphs checkbox, take a deep breath, and know that substituted glyphs are not a big deal in InDesign. :)

For more on composition highlighting in preferences, check out Anne-Marie’s excellent post from a while back.

    I’ve noticed that the substituted glyphs setting is enabled on InDesign documents when Q2ID was used for QuarkXPress to InDesign document conversion.

  • Bob Levine says:

    I never thought about it before, Cari, but you’re right. I’ve seen that, too. I think it leaves the text wrap only effects text beneath option enabled also.

  • Cari Jansen says:

    @Bob yup, you’re right… Also issue with Super/Subscript size (going from memory here, it’s been just over a year since I last ran a Quark to InDesign conversion project with one of our regional newspapers)

  • Gilbert Rajkumar says:

    Thanks for the guide. It cleared my long time question. I have one more doubt on this. Is there any possibility to change the highlight color (i.e., Yellow color)?

  • Michael says:

    Just wondering where I find preferences and composition to make the fix?

  • Eddie says:

    Thank you. In my 15+ years I haven’t seen that one before.

  • Mona says:

  • Why is the text in my inbox blacked out? The new unread is in white.

  • Everything is very open with a precise description of the challenges.
    It was really informative. Your site is extremely helpful.

    Thank you for sharing!

  • Kim says:

    Thanks so much:)

  • Tom da Silva says:

    OK, That is not the problem, my substituted glyphs box is not checked. I have yellow highlighted lines of text some pale yellow, some saturated yellow. complete lines are highlighted, not partial lines or individual words. not necessarily complete sentences.

    What does it mean?
