I used \ to access the Technical Set 1 (the ISO one, not the DEC one!) repertoire (these characters actually HAVE Unicode codepoints but they're very sparse and substantially inaccessible... like, the tristate output is a WHITE TRIANGLE POINTING DOWN while some other symbol are mapped in the technical symbol area... I don't remember if the AC symbol (actually the low frequency AC symbol) is mapped to the SINE one or some strange tilde...). Since the '~' codepoint it's unused in this set I recovered the tilde glyph using\~ :P

The set is described here: 

http://www.itscj.ipsj.or.jp/ISO-IR/181.pdf

(I have the corresponding CEI EN 61287:1997 but it isn't free to distributeand anyway doesn't tell much more).

Why I didn't use the Unicode codepoints? Two main reason:
1) I wanted to keep the character manager based on arrays instead of, for example, a map
2) These code point aren't defined in most fonts (maybe none has them defined) so they wouldn't be typeable in the standard input box.
