'isoinfo' utility doesn't show correctly some file/directory names

When an ISO image is created with RockRidge and Joliet extesions, e.g. "genisoimage -o image.iso -J -r -iso-level 2 ./imagefiles", then the "isoinfo" utility doesn't show correctly non-ASCII characters (e.g. "á", "í", "ü", etc) of the file and directory names from the Joliet records corresponding to these files and directories. For example, this a piece of the output of the command
"isoinfo -J -l -i ./image.iso":

Directory listing of /

Expected file and directory names should be:
-Análisis&Diseño.txt
-Cañí
-Código.bin
-wlan
