Hi, (( My local encoding is utf-8, so the source file seems to be the same as well: > file main.cpp main.cpp: c program text, UTF-8 Unicode text ))
I think I have found the bug which causes this: https://bugreports.qt.io/browse/QTBUG-70732 I am currently working on a workaround, I am now able to list the files now using <dirent.h>: QStringList results; DIR *dir; struct dirent *ent; QByteArray bpath = path.toUtf8(); if ((dir = opendir (bpath.constData())) != NULL) { /* print all the files and directories within directory */ while ((ent = readdir (dir)) != NULL) { results << ent->d_name; } closedir (dir); } else { /* could not open directory */ perror (""); } return results; This gives back the files successfully, the downside is that they are in UTF-8 normalization format D (UTF-8-mac) which represents accented characters like O" format, so the original character (O) + the accent ("). Similarly as "ls -1" does. And having a QString like that does not match "normal" (== "normalization format C") UTF-8 strings. Eg.: QString ch1("\u00D6"); // this is normal representation of "Ö" QString ch2("O\u0308"); // this specifies O with an accent qDebug() << ch1 << ch2 << (ch1 == ch2 ? "matches!" : "does not match"); This outputs: "Ö" "Ö" "does not match" not only on mac, but even on linux. So I also needed to convert "utf8 to utf8" :) for my complete workaround. Unfortunately I did not find a way to do so with QTextCodec. (Is there?) So I am trying now iconv... this seems to do the trick, but quite ugly and inefficient. QByteArray utf8_unmac(const QByteArray &utf8_mac) { iconv_t conv = iconv_open("UTF-8-mac", "UTF-8"); if (conv == (iconv_t)-1) { RAISE(TestRunnerException(QString("Iconv open failed: ") + sys_errlist[errno])); } char *inp = const_cast<char *>(utf8_mac.constData()); // iconv is moving these thats why the duplication size_t inp_len = utf8_mac.size(); size_t out_len = inp_len * 2; QByteArray utf8; utf8.resize(out_len); char *out = utf8.data(); if (iconv(conv, &inp, &inp_len, &out, &out_len) == (size_t)-1) { RAISE(TestRunnerException(QString("Iconv convert failed: ") + sys_errlist[errno])); } utf8.chop(out_len); iconv_close(conv); return utf8; } Hope it is useful for someone. To be honest, I always imagined that if everyone would use UTF-8 life would be much better, now I'm unsure ;) Br, Robert On 11/15/18 9:49 AM, Olivier B. wrote: > What is the encoding of your source file? > QString constructors interprets char* as if they are UTF-8.
