| − | In various word processor programs, | + | In various word processor programs, highlighting text, whether by clicking-and-dragging or double-clicking, it is easy to highlight characters which have no visible effects when markup is applied (ie ''italics'' or '''bold'''), such as a space or the end-of-paragraph passage. Since in most fonts the word space looks identical between the bold, the italicized, and the regular, this has no effect on how the end user will read the document, but could theoretically cause a problem in certain occasions, most notably in computers which might parse a bold space differently or incorrectly. This problem is compounded if the text cursor does not indicate clearly the space is in bold or italics when a user hovers their mouse over it. Randall worries about this. |
In the pictured case, Randall does not appear to have selected the word by double-clicking, since the cursor is depicted past the end of the word instead of on top of it; rather, he has clicked-and-dragged the mouse cursor to select it. The space character is a relatively thin character, which makes it hard to avoid and to notice, but even so most people don’t worry if they've selected it and tend not to bother fixing. Randall later uses the same click-and-drag method to have the bold removed, but this time omits the space, retaining its bold formatting on that character. Since it is a blank character, there is no easy way to tell it is still bold — even if it is slightly longer in the bold font, this may be hard to notice. This is the situation the comic is highlighting, [[559: No Pun Intended|no pun intended]]. | In the pictured case, Randall does not appear to have selected the word by double-clicking, since the cursor is depicted past the end of the word instead of on top of it; rather, he has clicked-and-dragged the mouse cursor to select it.

| − | Though Randall is likely thinking of computer-related problems caused by his invisible formatting, there is also a chance that his bold space would cause other, non-computer-related issues. As Randall has bolded the word "not" but then changed his mind, it indicates that he believes writing '''not '''is too strongly-worded. With an invisible bold space, whoever the document was intended for could notice Randall's bold space and figure that the word "not" was originally bolded. Depending on the context, a bolded "not" could be enough to change the tone of the text from polite and formal to dismissive (eg. "We believe you are not suitable for this position." vs "We believe you are '''not '''suitable for this position.") | + | The comic also indicates that Randall bolds text via clicking the "bold" button in the word processor, rather than using a keyboard shortcut (usually Ctrl+B or Cmd+B). Since the keyboard shortcut to bold - as well as italics, copy, paste, and print - are very commonly known shortcuts, clicking on a GUI as well as dragging to highlight a single word rather than double-clicking could indicate that Randall is not familiar with using word processors. |

In the title text, Randall says that he “fixes” this by running the text through {{w|Optical character recognition|OCR}}, which turns physical copies or images into text. Although this would "fix" the invisible formatting (since the OCR is unable to detect it), this would usually ruin even more formatting, and add inaccuracies to the text. This way, no one can tell which bugs were introduced by him and which ones by the OCR, which he facetiously suggests is better somehow. | In the title text, Randall says that he “fixes” this by running the text through {{w|Optical character recognition|OCR}}, which turns physical copies or images into text.

Real-world examples are governments changing the impact of reports for political reasons. Attempted tampering of this kind can be revealed by bold spaces. Another example would be a casual and short one-sentence reply e.g. to a romantic interest, which one takes one hour to formulate to sound as natural as possible. |

Randall’s background in {{w|computer programming}} could also make him more attentive to these types of technical problems, and therefore add this as a reason for his worries about invisible formating. |

*Bold (or italic or non-breaking) spaces are also popular in {{w|Steganography|steganography}}.

In the older word processor {{w|WordPerfect}}, one could do this with the “Reveal Codes” feature, which showed you character codes, separate from the characters themselves, around the characters. For example, a bolded space would look something like "<span style="background:#34F5FF">[BOLD≻</span> <span style="background:#34F5FF">≺BOLD]</span>". |
Web sites which allow content to be edited by users but generate the formatting code automatically often have versions of the invisible formatting problem; for example, eBay listings which use anything other than the default font rapidly accumulate hard spaces, font end and begin transitions, and other invisible formatting if they are subsequently edited, which can slow page loading and cause other problems. This is also seen in blogs etc. | Web sites which allow content to be edited by users but generate the formatting code automatically often have versions of the invisible formatting problem; for example, eBay listings which use anything other than the default font rapidly accumulate hard spaces, font end and begin transitions, and other invisible formatting if they are subsequently edited, which can slow page loading and cause other problems.
