Question

In ancient time, we can specify all characters with chr(56)

For example, say the character is unprintable. We want to put it in a string. Just do

Dim a as string = chr (56)

Now we have UTF8 or unicode (or whatever encoding).

Say I want variable a to contain

             en space
             em space
           thin space
‌ ‌    ‌      zero width non-joiner
‍ ‍    ‍       zero width joiner
‎ ‎    ‎       left-to-right mark
 ‏    ‏       right-to-left mark

In fact, say I want to create a function that’ll get rid all of such characters from my string.

How would I do so?

I want the function to leave chinese, korean, japanese characters intact and then get rid really really vague ones.

Replace removes whatever you want. ChrW produces Unicode characters by code (to produce characters outside Unicode Plane 0 you need to concatenate 2 Char).

Something like:

Replace("My text", ChrW(8194), "");
