[gf_lowtext]

Description

Based on [string_truncate] tag created by John Burwell, gf_lowtext returns truncated text to specified chars without truncate words, and add a suffix at the end of the string. It takes three params: an input -text, the lenght of the output and an optional suffix for the output. If the result ends with truncated word, this tag will remove the remaining chars, and will return a clean string.
