Nota
The math content is converted to MathML inside the corresponding string if there is a special character or any mathematical expression in the string. For instance, if the kernel receives s = "2 <math><mo>.</mo></math> 17"
, the substring function won't return the expected value. In this case, you need to include the string previously through the code editor.
