VTTEST – National Replacement Character Sets

ISO-Latin-1

XTerm's default encoding is ISO-8859-1. Here is an example:

Example of ISO-Latin-1 (POSIX)

Those characters can be translated to UTF-8.
If no translation is done, you might see something like this:

On the other hand, there is no good reason for this (VTE):

British

ISO-8859-1 was supported starting with the VT320.

The VT220 provided National Character Replacement Characters.
The VT320 did extend this slightly.

In these screenshots, the replacement characters are shown highlighted.
Incidentally, not all of the VT220's characters have Unicode equivalents.
XTerm shows the ones that are in Unicode.
