The Unicode Standard has imposed for itself strict rules to guarantee stability.[1] This implies that when mistakes against these permanent rules are published, these mistakes cannot be corrected. Depending on the grade of strictness of a rule, a change can be prohibited or allowed. For example, a "Name" given to a code point can not and will not change. But a "Script" property is more flexible, by Unicode's own rules.

Anomalies [edit]
- U+0818 ࠘ samaritan mark dagesh and U+0819 ࠙ samaritan mark occlusion: Names mixed up.
- Corrected text, names swapped:
- U+0818 ࠘ samaritan mark occlusion (HTML:
࠘"strengthens" the consonant, for example changing /w/ to /b/) and - U+0819 ࠙ samaritan mark dagesh (HTML:
࠙indicates consonant gemination)[2]
- U+2118 ℘ script capital p (HTML:
℘℘): it is not a capital
- The name says "capital", but it is a small letter. The true capital is U+1D4AB 𝒫 mathematical script capital p (HTML:
𝒫)[3]
- U+FE18 ︘ presentation form for vertical right white lenticular brakcet (HTML:
︘): BRAKCET is spelled wrong. Since this is the fixed Character Name by policy, it cannot be changed.[4]
- In 2006 Unicode has published a list of anomalies in character names.[5]
Stability policy [edit]
Version 1.0 versus Version 2.0 Names [edit]
In version 2.0, Unicode changed many code point "Names" from version 1. At the same moment, Unicode stated that from then on, an assigned Name to a code point will never change anymore.
