Description

Under a locale where labels contain multi-byte character the tag dump is not formatted correctly since std::setw does not handle the UTF-8 encoding of the labels.

Example:
---------------------------------
$exiv2 SDC12345.JPG
Dateiname : SDC12345.JPG
Dateigröße : 2778887 Bytes
MIME-Typ : image/jpeg
Bildgrõße : 4000 x 3000
Kamerahersteller: SAMSUNG
...
---------------------------------

I suggest a simple patch to correct this.

Patch submitted r3539. Thanks for report this and for the patch.

This seems like an ingenious and simple fix. Being a native English speaker, I have no feel for i18n issues. If you're happy that this has been effective, then I am happy to accept your help!

Sadly, the fix broken the build on MSVC 2005.

I could add #ifdef _MSC_VER ... #else .... #endif and use the previous code on MSVC. However this would result in different output from MSVC builds and potentially break our test suite. For the moment, I'm going to rollback r3539.
