Special characters: (TM), (R)

[Phil Tomson]

I need to output a company name and legal requires that we put the
circle R after the name as in Zowcorp(R). In some other cases we need
the trademark (TM) symbol.

I did this to try to find them:

(0..255).each {|i|
puts i.to_s+" "+i.chr
}

But I didn't find them in there... Which makes me wonder if it's even
possible to output them this way. I know that to get them in HTML you
use ® and ™

`puts 174.chr` gives me a little (R) symbol that's rather difficult to
read, and `puts 153.chr` gives me a dotted square - so I guess it
depends on what terminal font you're using. I assume you're wanting to
do this in a terminal window? The answer probably is that there's no
guaranteed portable way to do it except for "(R)" and "(TM)".

I think you're right. Now that I'm on a LInux box I see the (R) char
(puts 174.chr) but I don't see the (TM) symbol (puts 153.chr).
Previously, I was trying this on Windows and saw neither of them.

Hi,

It looks like a character encoding issue... When I set my terminal to
use the "Western (Windows Latin 1)" encoding, I can do this:™=> nil
But with it set to unicode (the way I usually have it), it give nice
little question marks instead of characters. I think Tim is right, in
the terminal, you may want to use (R) and (TM). If you are using it in
a cgi script, though, just set the character encoding correctly and you
should be okay.

Hey! great link! I'd been meaning to read up more on unicode, but
hadn't found enough information in one place... I read the first bit,
and it looks good (and it's not too dry, either).

Hi!

* Phil Tomson:

I need to output a company name and legal requires that we put the
circle R after the name as in Zowcorp(R).

In my complete list of ISO 8859 charsets I only find ® in

ISO 8859-1 (West Europe)
ISO 8859-8 (Hebrew)
ISO 8859-9 (Turkish)
ISO 8859-13 (Baltic Rim)
ISO 8859-14 (Celtic)
ISO 8859-15 (West Europe)

ISO 8859-2 through -7 and -9 through -11 (-12 does not exist) don't
contain it.

In some other cases we need the trademark (TM) symbol.

(TM) cannot be found in *any* of the ISO 8859 standard charsets. It
also cannot be found in any of the DOS codepages, EBCDIC codpages or
ISO 646 charsets I know (and I am quite sure to know all of them).
The only charsets I found them in are Windows codepages and Unicode.

Unfortunately my knowledge of ISO 2022 is by far too limited to make
a statement about the codes defined by it.
