I don't know what you use to create Thyromanes, but in FontForge, you simply insert an anchor into the base glyph, and an anchor with the same name in the diacritic. Decent font engines then simply make the two anchors overlap. Usually, you'd use the same anchor for all diacritics that go above a letter. Seeing as I can't provide detailed instructions for how to do it in FontForge, I imagine this quick post is going to be applicable to anything you care to name, too :) You can also create base-diacritic ligature combinations (i.e. custom precomposed letters, without an associated Unicode character) in the usual way if you want something peculiar, e.g. German style ÄÖÜ where the diaereses are positioned within the letter. But in general, you wouldn't do this. (OTOH, the only font engine I've used with support for such advanced features, ICU as used in XeTeX (providing OpenType fonts in TeX), automatically places the diacritic above the letter anyway (i.e. higher above a h/T then t then s, when there's no anchor). I imagine this method is necessary with multiple diacritics, so if your font engine doesn't do it, I'd consider it buggy.) -- Tristan.
