Barley Script Schriftart
It is handmade by Måns Grebäck and works perfectly for logotypes and slogans.
The font contains a lot of alternate characters and ligatures to make the script simulate a handpainted logo.
With its hundreds of glyphs it also has support for a wide range of languages.
Write underscores before any word to make an underline.
If your software supports ligatures, you can write multiple underscores for a longer line.
