+ss06 feature provided by Old Standard. This feature is supposed to distinguish between regular and ‘curled’ beta (β/ϐ) and to print ‘curled’ beta (U+03D0) in medial position. This feature worked in most cases with the previous release of Old Standard. However, it failed if the beta is preceded by a vowel with an acute accent taken from the Greek extended Unicode block.At the time of writing, Old Standard was last updated six years ago. Being unable himself to contact the author, the writer, while in need to have new letters included in Old Standard and some issues addressed, took the decision to make a new release of Old Standard.
