Fixed Build 48 - Non-ASCII Character mishandling

I use the "box-drawing characters" of codepage 437 in many tables presented by batch programs. In one of my batch files, unchanged since V8 (though it could be made more efficient), all versions from V7 through V13.03 B46 always display the xB3 (vertical bar) character correctly. On two separate systems B48 does not.

In a batch program which uses the line below

set zz_bal=%@eval[%@field["│║",4,%line]]

the field delimiter is reported to be "" in B48.

I suspect the new UTF-8 processing has caused this problem. I did not change my .INI files to accomodate UTF-8 which I do not use; my V13.INI was last changed [email protected]:33:52, when B45 was the installed release.

This bug is a show stopper!
