utf8Title (class Utf8Title) Applications can set xterm's title by writing a control sequence. Normally this control sequence follows the VT220 convention, which encodes the string in ISO-8859-1 and allows
for an 8-bit string terminator. If xterm is started in a UTF-8 locale, it translates the ISO-8859-1 string to UTF-8 to work
with the X libraries which assume the string is UTF-8.
However, some users may wish to write a title string encoded in UTF-8. Set this resource to "true" to allow UTF-8 encoded title strings. That cancels the translation to UTF-8, allowing UTF-8 strings to be displayed as is.
