If you have ever tried making a custom linetype with inch symbol (“) in the linetype definition, you know AutoCAD will complain, because it interprets this as an extra quote mark in the linetype string. Instead, use %%34 to represent the inch mark (“). See the following example:
*15 Inch,-----15"-----15"-----15"-----15"-----15"----- A,.5,-.2,["15%%34",standard,S=.10,R=0.0,X=-0.12,Y=-.06],-.2,.2
Note: The 34 is the ASCII code for (“)
