The MS Knowledge Base has the following article on old (obsolete)fonts, a category which includes MS LineDraw. The article states Courier New includes MS Linedraw as a subset, and that recent versions of Word make automatic substitutions.
But it may be that this is not something that need be of concern to UFT users, except out of curiosity. If it is of concern to TMG users, that too will probably pass with the release of TMG 5.
But for the curious who do not have the latest versions of Word or Windows, it may be possible to trick PAF 5 into an Options-symbol mode that will show a Character Map of subsets of various character sets, including the latest Unicode "font" versions.
