I can't edit or delete posts in this subforum. Pete or Solitaire would have to do it.
As it seems you've figured out, you need to use NBSP (Alt+255 or Alt+0160). You can do use notepad to search and replace spaces with NBSP characters, or use a program like this:
'public domain, michael calkins
DIM i AS LONG
DIM b AS STRING * 1
DIM t AS STRING
LINE INPUT t
IF t = "" THEN t = "delme.bas"
OPEN t FOR INPUT AS 1
OPEN t FOR BINARY AS 1
OPEN "---tmp.txt" FOR OUTPUT AS 2
OPEN "---tmp.txt" FOR BINARY AS 2
FOR i = 1 TO LOF(1)
GET 1, , b
IF ASC(b) = &H20 THEN b = CHR$(&HA0)
PUT 2, , b
SHELL "notepad ---tmp.txt"
