This failure relates to:
The objective of this failure condition is to avoid the use of ASCII art when a text alternative is not provided. Although ASCII art is implemented as a character string, its meaning comes from the pattern of glyphs formed by a visual presentation of that string, not from the text itself. Therefore ASCII art is non-text content and requires a text alternative. Text alternatives, or links to them, should be placed near the ASCII art in order to be associated with it.
The following ASCII art chart lacks a text alternative and therefore does not meet SC 1.1.1. Note this failure example does in fact cause this page to fail, but you may skip over the example.

Access a page with ASCII art.
For each instance of ASCII art, check that it has a text alternative.
If check #2 is false, then this failure condition applies and the content fails this success criterion.
