What to call the characters-based decoration found in many announce emails


Many emails received from Japanese companies contain characters-based
[dingbat](https://en.wikipedia.org/wiki/Dingbat)-style ornament like this:

[code]

    ■□■□■□────────────────────────────  
    blablablablablablablabla  
    ────────────────────────────■□■□■□
    
    ■blabla  
    ｜　bla：blablabla  
    ｜　bla：blabla
    
    ■┓　　bla 　　┏■  
    ┗┛━━━━━━━━━━┗┛  
    ...
    
[/code]

It seems to be a particular case of [Shift_JIS
art](https://en.wikipedia.org/wiki/Shift_JIS_art) (which I don't know how to
say in Japanese either, by the way).

What do you call this type of email decoration in Japanese?
