Failure to initialise Unicode font library

My RPi has suddenly developed an inability to load NetSurf:

The Unicode font library could not be initialized. Please report
this to the developers.

and James Bursa's Sargasso:

Failed to initialise Unicode font library

Both of these apps were working perfectly in France on 4/12/17, but the
problem cropped up on my reconnection on my return home.

Thinking this was a problem with a shared resource as it affected two
applications, I restored my previously backed-up Boot:Resources directory
in its entirety, as I did not know which particular resource would produce
this error, but to no avail.

Any suggestions as to what to look at next?
