Subject: Re: U+25CA LOZENGE - why is it in the "Mac OS Roman" character set
(and therefore widespread in current fonts)?
To: Robert Wheelock <rwhlk...@gmail.com>


Dear Robert,
you have sent the mail below to my private address but I presume that
it was intended for the Unicode list.
Please resend it to unicode@unicode.org. I will answer you there, as I
in fact was engaged in that subject before.

Best wishes
Karl

RW>  "Raute" is:
RW>     a. lozenge
RW>      b. the viewdata square in the now discontinued Bildschirmtext
RW>        (which roughly corresponds to Viewdata, Videotex or Prestel
RW>         in other countries.)
RW>  "Nummernzeichen" (literally: number sign) is a collective term for
RW>      "#" and the "Numero-Zeichen" № U+2116 NUMERO SIGN, as using it
RW>     specifically for "#" would cause confusion, as the "#" never was
RW>     used for marking numbers except on desktop calculators, and the
RW>      name in fact was used for the NUMERO SIGN also.
RW> Then, I extended and edited the Wikipedia articles according to this
RW> scheme.

RW> Now, after discussing this with several people, I learned that this
RW>  scheme was too academic, as in fact everybody seems to call the "#"
RW> "Raute". The word "Raute" otherwise is unused in colloquial German.
RW> You learn in math lessons that there is a geometric form called
RW>  "Rhombus" (lozenge) which also can be called "Raute", but in the class
RW> "Rhombus" is the preferred term. "Raute" also is the preferred term in
RW> heraldics, but used by the general public only when referring to the
RW>  pattern of the Bavarian flag. (Besides, "Raute" is used in the name
RW> of some herbs, like Ruta graveolens, but also only by specialists.)

RW> The lozenge usually is called "Karo" in colloquial language (like the
RW>  diamond suit on playing cards), and only "Rhombus" when it deviates
RW> too much from a square standing on its corner.

RW> Thus, when the "#" came as a new character to the general public
RW>  with the keypad telephone in the 1970s, together with a name "Raute"
RW> which sounds not unknown and not really wrong, thus it got its way
RW> into the general public together with the "#" (which, as said, was
RW>  formerly not used in Germany).

RW> "Raute" is e.g. used by customer services which you call when you have
RW> a question regarding your mobile phone, and you are told to press the
RW>  lower right key on your telephone keypad.

RW> On the other hand, as far as I know now (and a DIN officer confirmed
RW> me this), there is no German standard which uses the term "Raute".
RW>
RW> Thus, I probably will use the term "Doppelkreuz" but have to remark
