/*
|
|
* XXX - "isprint()" can return "true" for non-ASCII characters, but
|
|
* those don't work with GTK+ 1.3 or later, as they take UTF-8 strings
|
|
* as input. Until we fix up Wireshark to properly handle non-ASCII
|
|
* characters in all output (both GUI displays and text printouts)
|
|
* in those versions of GTK+, we work around the problem by escaping
|
|
* all characters that aren't printable ASCII.
|
|
*
|
|
* We don't know what version of GTK+ we're using, as dissectors don't
|
|
* use any GTK+ stuff; we use GLib as a proxy for that, with GLib 2.x
|
|
* implying GTK+ 1.3 or later (we don't support GLib 1.3[.x]).
