In some cases character modifications are not read aloud by audio browsers. For example, strike through lines are not read aloud, ending up relaying an exact opposite meaning.

Bad example: Display only with a strike through.

Good example: Display the "cancellation" in text.
Some audio browsers do not read aloud the intended text symbol. Please avoid only using symbols to display important information. Pictographs (ASCII art) are not read aloud as intended. Please do not use pictographs, but instead use characters or images. Machine-dependent characters also lead to mistaken display, so please avoid using these as well.

Bad example: and may not be read aloud

Good example: Audio browsers can make sense of the symbols with the text also provided in brackets.
