Getting strings with special char such as #

[WifiWall]

Hello,

We try to have special chars in string fields, for example, passwords. When the string include # for example, it acts as if this is a comment and the string is incomplete:

Password=AB1#5T

We also try:

Password=AB1#5T - using escape

And we tried:

Password='AB1#5T'

Second comment:
When we add a single quote for example:

Password='ThisIsMyPass'

The returned string is: 'ThisIsMyPass' so we get the single quotes).

Is there a way for putting special chars in the strings and also is there a way to not getting the single quote in the returned string.
