Using Xe(La)TeX, how could the hyphenation character be set to any particular glyph in a given font? I'd also like to have the possibility to set a color for the glyph when used for that task and to set the glyph's size, too.
I am thinking of using some ornamental glyph as hyphenation character, but haven't figured out how to put to good use the facilities of the package
fontspec to this end. I've tried with the key
HyphenChar, but I wasn't able to set a value in terms of
XeTeXglyph when I found a glyph not corresponding to any UniCode number; besides, I had no chance to set either color or size.
