Hi Rich,
"Latin-US (DOS)" is not shown under "File/ Reopen Using Encoding". Only "Western (ISO Latin 1)", "Western (ISO Latin 9)" and "Western (Windows Latin 1)" are included there.
If I open a text document in BBEdit, use the status bar at the bottom of the window, and choose "Other" in the encoding list there, then I am shown a longer list of encodings, among which is included "Latin-US (DOS)", which I can then select for that specific document.
However, as I noted earlier, from my research into this -- and web scrounging -- it seems that very few fonts actually contain the full CP437 set of high ASCII characters. I only found three of them:
ASCII.ttf
dos437
Modern DOS 437
All three of the above fonts contain the full set of CP437 high ASCII characters.
Last month I installed all three of these fonts via the Font Book app.
In the OS X Terminal app, in my chosen theme -- Homebrew -- I can use any one of those three fonts, and PC-ANSI graphics will display properly when I visit my BBS, or any other BBS. "ASCII.ttf" definitely works the best of the three for me, in conjunction with other adjustments that I make in my Homebrew settings.
However, as I explained earlier, if I open one of my ANSI graphics files in BBEdit, and choose any of those three fonts, along with the "Latin-US (DOS)" encoding, or any of the others that I mentioned, the high ASCII characters do not display properly.
In other words, when I say "without success" I mean that I do not see these special characters, which, as you know, are what is used to draw PC-ANSI graphics for BBSes, such as mine. I see garbage instead:
Also of note is the fact that control-left bracket -- which is used to make the little arrow that is in front of PC-ANSI color codes -- cannot be used in BBEdit either. When I type that key combination. Nothing happens, and no symbol appears in the document.
I was really hoping that I could do this in BBEdit, because right now I use the Public Address BBS software -- which has a built-in PC-ANSI graphics viewer -- to make all of the graphics for my BBS. As with my BBS software -- Hermes II -- I am forced to run this in a virtual environment using SheepShaver. My vision has been rather poor all of my life, and even more so now that I am in my sixties, so making ANSI graphics in that environment places a real strain on my eyes. I was hoping that by using BBEdit, I could use a larger size font, and thus reduce the strain on my eyes when I make my graphics. In fact, in everyday use, I keep BBEdit set to 24-point Monaco font, because it is large and clear without serifs.
