http://home6.swipnet.se/~w-61277/rattsatt/runlitt.pdf describes a font that has glyphs for combining inverted breve glyphs that streach over 2-6 letters... (the letters underneath the sample glyphs are just examples to show the width; the font also has different glyphs for different vertical positions instead of using a calculated position). I don't know how commonly they are used, but apparently they are used... (The font is intended for transliterated, into Latin script, Runic texts where 'bindrunor' (Runic ligatures) are marked.) /Kent K
