[XeTeX] lacking precomposed character

[John Was]

Yes - it would make sense to have \leavevmode at the start of \overstrike 
and then it would always work.  The code is very hamfisted - done in my 
first few weeks of acquaintance with The TeXBook (decades, or at least 
lustra, ago...) - and I've never produced a neater version or attempted to 
make it more robust.  But it's surprising how often it's got me out of an 
awkward situation, particularly (in pre-XeTeX days) with superimposed 
diacritics, since it can be nested, with \raise \hbox commands as one of the 
elements - so you can have macrons and acutes piling up, for example.
