Character Style changes leading of Paragraph style

It may be a difference with how each font fills the type slug. I'd suggest:

• Try changing the Character Style back to Avenir with the Preview check box on and see if it fills the type slug better. If it does, then change it back to Avenir Next Condensed and see if the problem reoccurs. Or not.

If it does reoccur, you may have to fiddle with the baseline shift to get the font to line up right and apply that to your Character Style in the Advanced Character Settings section. If just switching back and forth fixes the problem, chalk it up to a quirk of the system and press on.

Good luck,

I would try creating a new character style that is fresh and deleting the old character style and replacing it with the new character style. While rare, styles can sometimes seem buggy.

If the document is beginning to corruct, OTOH, export to IDML and re-open that resulting file. Maybe the odd behavior will go away.

My bet is that when you specify no leading, you're actually getting [Auto] leading, or 120% of the character size.

You have to specify your leading in the character style as the same in your paragraph style if you want to avoid rude surprises.

Hope this helps,

Randy

Are there any + sign overrides on the text? Is the paragraph style calling for an explicit value of leading? Not auto-leading? Is the character style really empty of the leading value? Is the last invisible hard return character (the pilcrow) being selected when you apply a paragraph style?
