Re: display _ as left arrow (was Re: Help on sending a UDP Packet)

[address@hidden]

If I understand the footnote in the GNU Smalltalk syntax on := and _ correctly, 
no Unicode is required anyway:

The GNU smalltalk manual says:
" In the ancient days (like the middle 70’s), the ASCII underscore character 
was also printed as a back-arrow, and many terminals would display it that way, 
thus its current usage. "

So it would be sufficient to find a font that displays _ as back-arrow,
which according to the above would exist for simple ASCII -- without Unicode 
extensions.

There are footnotes in the wikipedia page on ASCII

https://en.wikipedia.org/wiki/ASCII#cite_note-Haynes_2015-60

that up arrow and left arrow were in use.

It says:
"By 1967 the underscore had spread to ASCII,[5] replacing the similarly-shaped 
left-arrow character"
