The majority of them are treated as graphic symbols that are not characters.  Exceptions to this include characters in certain writing systems that are also in use as political or religious symbols, such as 卐 (U+5350), the swastika encoded as a Chinese character (although it is also encoded as a religious symbol at U+0FD5); or ॐ (U+0950), the Om symbol which is, strictly speaking, a Devanagari ligature. A special case is ﷲ (U+FDF2), which is a special ligature of Arabic script used only for writing of the word Allah. This ligature is in the Arabic Presentation Forms-A block, which was only encoded for compatibility and is not recommended for use in regular Arabic text.
Unicode defines the semantics of a character by its character identity and its normative properties, one of these being the character's general category, given as a two-letter code (e.g. Lu for "uppercase letter"). Characters that fall in the "political or religious" category are given the "general category" So, which is the catch-all category for "Symbol, other", i.e. anything considered a "symbol" which does not fall in any of the three other categories of Sm (mathematical symbols), Sc (currency symbols) or Sk (phonetic modifier symbols, i.e. IPA signs not considered letters).

Ostensibly religious symbols are, however, not limited to this section, as the same chart has another short section of two characters labelled "Syriac cross symbols", with the explanatory gloss "These symbols are used in liturgical texts of Syriac-speaking churches". Another short section of two symbols is headed "Medical and healing symbols", including U+2624 ☤ Caduceus (c.f. U+1F750 🝐 "alchemical symbol for caduceus"), U+2695 ⚕ Staff of Aesculapius, and U+2625 ☥ Ankh, all of which originate in polytheistic religious traditions.
