When  I try to create a new linetype with express in 2024.....standard text will workHowever when I try to make a linetype using a symbol or subscript the text does notshow in the drawing...the  line and spacing is there.uploads/118036/Drawing1.dwg

Try the LTFly utility (see Download) for better creation of text-based linetypes. You will need to specify the superscript as a unicode character (\\U+nnnn).

MKLTYPE doesn't accept Mtext [even without internal formatting such as for a subscript], which you could have known from its Express Tools Help description.You can make the O and the 2 separate Text objects [just Explode your Mtext with the subscript], and MKLTYPE can handle their different sizes and vertical positions.  Using the components in the upper part of this image [I Exploded the Mtext], it made the linetype of the lower part.
