About this font family
Catfish is a monoline geometric script with a touch of classic and vintage and can be used for various purposes such as logos, badges, t-shirt design, signage, labels, book cover design, posters etc...
The font is best used in an OpenType-aware software such as Adobe Illustrator, InDesign, MSWord etc. Please note that OpenType capabilities differ from one application to another. Underline feature was tested in Illustrator, InDesign, Photoshop and MSWord and works perfectly.
The package contains a how-to pdf explaining how to use the underline feature.
If you are working in Adobe Photoshop, to get an access to all glyphs you may need an additional software (for example, PopChar http://www.ergonis.com/products/popcharx/).
