OSD: On Screen Display and 'forbidden' characters / symbols

Sometimes you run into the situation that you want to use a character in the On Screen Display (OSD) what is not allowed. An example of a character that is not allowed is,   ‘+’.

A workaround to get the  ‘+’ in the OSD, is adding the following sequence in the OSD: \uXXXX
Where XXXX is the hexadecimal code of the character.  
Example, for the character ‘+’ the sequence becomes \u002B



In the ASCII table below, there are next to the column with ASCII codes, also
columns with Hexadecimal codes and the column with the characters.
Example (ASCII   Hex   Char):  043   2B   +
