Hello Bloomie and other Brush Scripts

Has anyone placed a text border on a Hello Bloomie font in InDesign? All of the "brush" fonts have a ragged border, but Hello Bloomie letters seems to have some kind of hidden frame which scatters little dots around the area marking the frame of each letter. I thought it was the text frame, but it wasn't. This seems to happen only with contrasting colors, not black on white (paper). None of the Script/Brush fonts I tried had this problem. I ended up using a similar Adobe font (Tough Love) but need to learn more about the behavior of Adobe fonts--fills, borders and effects. Thank you for your attention.
