You can if, as jmt pointed out, one of the characters (the dot, in this 
case) is a Unicode combining diacritical mark.  At least you can in 
systems I've used, for most fonts.  Systems I've used in this case means 
XeLaTeX (a Unicode-aware version of LaTeX) and Microsoft Word.  I have 
not used the XSL-FO transform, but hopefully it works there too.


There may of course be Latin fonts where the dot-over is not defined, 
and there might possibly be fonts where it is defined but where it 
doesn't position itself correctly over some base characters 
(particularly where there is more than one diacritic, i.e. stacked 
diacritics).  Fonts should come with a chart that tells what code points 
they handle, but that information can sometimes be difficult to find.

You cannot combine multiple characters to form the composed one. If there is 
Unicode character for this combination, you can use it directly. If it is not 
displayed correctly, it means your font doesn't contain this character and you 
need to switch to the font with broader character support.

If there is no suitable Unicode character nor appropriate font, the only way is 
to use the inline image, ideally vector one, e.g. SVG.

Re: [docbook-apps] Capital latin "Q" with dot above

2018-06-12 Thread jmt
Unicode provides "combining diacritical marks" : you can use
"COMBINING DOT ABOVE", the hexadecimal value of which is 307 :

in xml :
Q

in text, on a linux platform (Hold down the shift and control keys
while typing 'u' and the hex value)
Q̇


Please note that result is dependant on the font you are using ; but it
works for most standard (browser) fonts.

More information is available at
http://www.unicode.org
and charts
http://www.unicode.org/charts/
can be helpful (I have local copies available when working with
docbook !)
