Thanks, Duncan! This works for the particular case and is, to my mind, a great solution!
However, I was wondering: is it possible to use these double dots with another character, such as omega? I apologize for changing the question somewhat, but I did not realize earlier that there were separate codes for putting double dots over different letters and I thought that figuring out the simpler question would be enough for me to figure out the next step. Thanks again! Best wishes, Ranjan On Sun, 14 May 2017 23:57:50 +1000 Duncan Mackay <dulca...@bigpond.com> wrote: > Hi > > I just had to do something similar in windows with \"{u}.
