This is a limitation of the Microsoft RichTextBox. I discovered that the character \u1? appeared to function as a hardspace. This is only used when the text is displayed and not when it is edited, so, you need to move off the window to see the effect.

// This is to fix an issue with Hard Spaces. To Summarize:
// The Microsoft RichTextBox has a problem with hardspaces, that they don't work between numbers and lettters
// This is the majority of cases for PROMS including ROs (Sepoint Number and Units) and transtions (Step ###)
// As I investigated this further I found that if you pass a rtf unicode value for a hard space (\u160?) to
// the RichTextBox, the RichTextBox will return an ASCII representation (\'A0). If you pass an ASCII representation
// the RichTextBox will return a space.
// Alternatively, If you pass a unicode representation of zero (\u0?) it acts like a hard space and returns an ASCII
// representation (\'00). If you pass in the ASCII representation, it truncates the text.
// The following two lines replace hard spaces (ASCII) with the UNICODE represntation of Zero.
// Lastly, If you pass a unicode representation of one (\u1?) it acts like a hard space and returns an ASCII
// representation (\'01). If you pass in the ASCII representation, it keeps the ASCII representation.
// The following two lines replace hard spaces (ASCII) with the UNICODE represntation of Zero.
// Other characters which behave like hard spaces are 28-31 and 128-159.
