Unicode anomaly
 | This article needs attention from an expert on the subject. Please add a reason or a talk parameter to this template to explain the issue with the article. (November 2010) |
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
- U+0818 ࠘ SAMARITAN MARK OCCLUSION and U+0819 ࠙ SAMARITAN MARK DAGESH: Names mixed up.
- Corrected text, names swapped:
- U+0818 ࠘ SAMARITAN MARK OCCLUSION ("strengthens" the consonant, for example changing /w/ to /b/) and
- U+0819 ࠙ SAMARITAN MARK DAGESH (indicates consonant gemination)[2]
- U+2118 ℘ SCRIPT CAPITAL P (℘, ℘): 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 (𝒫)[3]
Stability policy
Version 1.0 versus Version 2.0 Names
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.
