Reply To: Rogue font in my style?

Perhaps and en space isn't available in the font that you have choosen.

Search for all en spaces and change it to another font that has the en space glyph

Probably best to test one or two en spaces and fonts first, if you make a character style for your en spaces it may help speed things up, as you can include the character style in a nested style or Grep Style that will find en spaces and change them to the character style you need on the fly.
