Ti ringrazio dell’ottimo suggerimento. Aprendo il file updmap.cfg ho trovato questo metodo che pare risolva il problema della sovrascrittura in aggiornamento:
# The full updmap.cfg is generated by concatenating updmap-hdr.cfg with
# all the Map and MixedMap lines from an installation, possibly
# appending a local configuration file.
#
# To make local customizations to the map files, please use of the
# following methods:
#
# 1) call
# updmap-sys –enable Map=foo.map
# for each map file. (Or MixedMap instead of Map, if your font has
# both Metafont and outline definitions.) See the updmap –help
# documentation.
#
# 2) add your local map entries to the file
# TEXMFLOCAL/web2c/updmap-local.cfg
# and then call
# tlmgr generate updmap
# which will concatenate updmap-local.cfg to the end of the final
# updmap.cfg. (You can override the local.cfg file location with the
# –localcfg option; see tlmgr –help.)
#
# If you use either of these methods, your local adaptations will be
# preserved when tlmgr updates the installation or this config file.
# Manual edits to updmap.cfg may be lost on update.
Ti riporto integralmente l’inizio del mio file updmap.cfg. Ho applicato il metodo 1 inserendo MinionPro.map al posto di foo.map e poi ho comunque copiato dove mi hai suggerito.
Molte grazie. Speriamo che risova il problema dei font.
