I am having a bit of a problem regarding chr(0)

Basically, I need to send Chr(0) as part of a string to a POS Printer (it resets the font to the standard size, family etc)

However Chr(0) seems to be a black hole.

As soon as it is added to a stringbuilder, anything appended after it disappears.

It I concatenate strings (ugly and inefficient, I know) it also makes and extra string additions disappear!

Can anybody suggest anything?
