The following paragraph is an extract from WP:SORTKEY.
 * To place entries after the main alphabetical list, use sort keys beginning with tilde ("~"). Several Greek letters are also used for specific purposes. "Σ" (sigma) is used to place stub categories at the end of subcategory lists .... "β" (beta, displays as "Β") is for Wikipedia books. "ι" (iota, displays as "Ι") is for images. "ρ" (rho, displays as "Ρ") is for portals. "τ" (tau, displays as "Τ") is for templates. "ω" (omega, displays as "Ω") is for WikiProjects. Similar to the handling of Latin letters, if the sort key is a lower case Greek letter then the capital Greek letter will be displayed in headings on category pages. "β" will appear beneath "Β"; "ι" beneath "Ι"; "ρ" beneath "Ρ"; "τ" beneath "Τ"; "ω" beneath "Ω"; etc. ...

The following table provides further information about the use of these sortkeys. The examples are intended to be consistent with WP:SORTKEY and other Wikipedia guidance/policy.

Other special purpose sortkeys that have been used include:
 * " " (space) - typically used when an article is categorized in an eponymous category.
 * "*" (asterisk) - e.g. here where the correct (per WP:SORTKEY) sortkey was replaced with an asterisk.
 * "ε" - to (incorrectly) place a "needing expert attention" category in a content category.

Note: Code such as  can be used.
