Underscore not visible

Hello,

Although it exists in the text (proven by copying and pasting the text to a text editor), the underscore character “_” is not visible when used in Syntax Highlighter. Apparently, it is being overwritten (painted over??) due to the use of the CSS style of 0 padding.

For example, if you go to the page supplied by the link https://rubynator.com/?page_id=251 and search for the text “Range” you will see:

my values = my array[MYRANGE]

even though the text is:

my_values = my_array[MYRANGE]

If I go to the developer tools (F12) and edit the CSS, changing the padding to 1px (or simply disabling the padding characteristic for the style) resolves the problem.

Is there a mechanism available to ensure that the underscore will be visible when the text is displayed?

I much appreciate your help on this.

Best Regards,

Edward
