At the moment, I use “\,” between word and question marks. Also “~” between word and “:”. I guess the \definecharacterspacing is more flexible and transparent from text input point of view (only write normal space). IIRC both \, and ~ also avoids line breaking at their location. Is there a way to specify this too please ?

Could not find any occurrence on the Wiki. The best description I have seen of it is in Wolfgang’s message on the mailing list at http://www.mail-archive.com/ntg-context%40ntg.nl/msg77942.html (or http://www.ntg.nl/pipermail/ntg-context/2015/081569.html if you prefer pipermail navigation). Basically, define the spacings you want with \definecharacterspacing[myspacing][…][…=…,…=…] and put them in play with \setcharacterspacing[myspacing]. Do it within a group to have it apply only within that group, or apply it globally. Sorry, no help here for the installation issue. -- Rik
