http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52539 Tobias Burnus burnus at gcc dot gnu.org changed: What|Removed |Added CC||burnus at gcc dot gnu.org --- Comment #2 from Tobias Burnus burnus at gcc dot gnu.org 2012-03-10 14:52:51 UTC --- (In reply to comment #1) I remember this being discussed before. Lets check the standard regarding encoding for namelists. Well, the issue already occurs for list-directed reading (read(99, *) str2). One finds in F2008, 10.10.3p7 for list-directed read and in F2008, 10.11.3.3p7 for namelist read: When the next effective item is of type character, the input form consists of a possibly delimited sequence of zero or more rep-chars whose kind type parameter is implied by the kind of the effective item. That clearly implies that it supports kind=4 (UCS-4, ISO 10646) characters - and there is also no wording that the file encoding (UTF-8) doesn't apply to list-directed read and to namelist read/write.
