qgetenv and special chars

[ComaWhite]

I think you would need to convert the 3 line to foo.toUtf8() and the 1st line implicitly coverts it to unicode. And cout STL doesn't handle unicode.

That could be a side effect of implicit char* to QString casts, or improper locale settings which would make QString::fromLocal8Bit() use an improper text codec.

[mimcimm]

The Qt environment manipulation functions are thread-safe, but this requires that the C library equivalent functions like getenv and putenv are not directly called.

To convert the data to a QString use QString::fromLocal8Bit().

Note: on desktop Windows, qgetenv() may produce data loss if the original string contains Unicode characters NOT representable in the ANSI encoding. Use qEnvironmentVariable() instead. On Unix systems, this function is lossless.
