Loveletter No. 9 was made for the love of letters, of course.
To underline words use the Underscore after the word or after three/four letters (width of the underline), for example "The_", "Lovelet_ter", "Question_", just for starters.
The width of the uppercase letters are set to be used as capitals, for full caps some extra space may be needed, otherwise words will look like long monograms.
Some of the letter pairings are based on heavy kernings, so it's better the font to be used with softwares that include this feature.
Even with all the love around the font is not free, to use it in commercial works please contact me or go to loremipsum.ro.
Thanks,
Levi
