View source for String x

===Purpose===
Add backslash before troublesome TeX characters.

===Synopsis===
:safestring = string_x(string);

===Description===

The TeX interpreter is used on various text objects in figures to add subscripts, superscripts and other special effects to text. These effects are triggered by special characters in strings. string_x "escapes" these special characters to keep them from being handled by the TeX interpreter.  An escaping backslash is added before each of these characters: _ ^ { }
 
====Inputs====
* '''string''' = a string to clean

====Outputs====
* '''safestring''' = the backslashed string
