Hi, First, thanks for replying. I appreciate it.

No, I don't think I implied that. I stated that I want to handle "raw" filenames gracefully, whatever the encoding that I couldn't tell and don't care. I understand what you are saying that if the original character set was not specified, there is no way you can detect it based on the bytes because of multitude of ambiguity. So, just call it "raw". A lot of times, it is adequate to interpret the byte sequence with best attempt. g_filename_display_name() did that (so this answered your "question"), except that I didn't like how the illegal character (now, U+FFFD) is rendered -- it looks seriously "broken" and somewhat annoying. It is better to show illegal bytes in an easier to understand manner, like octal escape sequence or hex, or even a question mark. Well, with g_utf8_validate(), it is trivial to implement a function that escape non-UTF-8 bytes to Hex. However, I then found out that TreeView, or more likely Pango, would unescape the %xx sequence (undo my attempt to help it) and choke!??! I'm now quite sure that it is not worth the effort to handle a case like this, even though I think it should be do-able and pain-free. (If not quite as many things in GLib that get in the way.) More random thoughts: Is there a way to ask Pango to render illegal UTF-8 bytes as the more pleasant rectangle with hex number in it (as in the case when the font is not installed), rather than printing out cryptic messages on the terminal?
