Holy cow, that took a long time to find what's going on...
The problem occurs when calling GetDirectories() when there are
directories with "high ASCII" characters (like "M�lodie Citronique").
The function glob(), which is used in FindFirstFile(), uses fnmatch(),
which uses mbsrtowcs(), to convert a multibyte string to a wide
character string.
I did not have any locale-related environment variables set. Since mono
calls setlocale(LC_ALL, ""), this results in mbsrtowcs() failing for
file names with extended characters.
If I set a LC_CTYPE, say to "C", the files make their way past
fnmatch(), but then there's a crash in FindNextFile(), where it tries to
convert g_utf8_to_utf16 and fails (perhaps because the input isn't
UTF8?). I tried adding a call to g_locale_to_utf8() but this failed as
well.
Help!!!! Can someone else shed some light on this? Easy to reproduce,
just create a directory with an accented character, and then run this
source.
What is my LC_CTYPE and other locale environment variables supposed to
be set to?
using System.IO;
using System;
class C
{
static void Main()
{
string dir = "./";
DirectoryInfo dirInfo = new DirectoryInfo(dir);
DirectoryInfo[] subDirs = dirInfo.GetDirectories();
foreach (DirectoryInfo subDir in subDirs)
{
Console.WriteLine("Directory is: {0}.", subDir.Name);
}
}
}
