# Is this a standard representation of a 'space' character?

I recently came across a handwritten note with directions to push a string of text into a database. There was a strange character in the string I've never seen before, a lower case 'b' with a forward slash through it:

I asked the author about it and he said it was an old-school way of representing a space.

My question is whether or not this was a standard/widely used representation of a space character and if so, whether or not it's still commonly used.

• @DavidRicherby - I get where you're coming from on that. What I'm after is the context in which it was originally used and whether it still has a use today. Hopefully that's clear by the question. – TheIronCheek Dec 13 '17 at 16:41
• @TheIronCheek Given the answer, it seems I was being overly pessimistic/skeptical. – David Richerby Dec 13 '17 at 18:02

ps. I also learned this symbol as Turing tape blank. I will check an old book later. Nowadays I would use B or if I am feeling adventurous ␣ 'open box' (U+2423) $\text{\textvisiblespace}$.
