Hija,

I get an exception (std.format string) thrown
after I read a file with std.file.read and try
to writefln its content, while it works fine
with toStringz and printf.

Code is something like:

char[] s=cast(char[])stf.file.read("name.ext");
printf("<%s>\n",toStringz(s)); // works fine
writelnf("<",s,">"); // exception generated

I have shrunk the file to:

garble"%"urgh

I do strongly suppose that the problem lies
somewhere in part saying "%" , but... ?

Is this a Hemiptera? :-)

Regards,

  frank

I think that your file has non UTF-8 characters inside (characters with
codes >= 128).

char[] is in D UTF8 sequence.

You probably should first recode your file.

unless it is being used from a format string, all char[] are assumed to be format strings. Try this:

writelnf("<%s>",s);

In general it is bad practice to have a non literal string used in writef/writelnf unless you only reference it by way of a format string.

Wow!  I never thought of that.  (sincerely)   I'll be sure to do that in the future.
