U+1F100–U+1F1FF (Enclosed Alphanumeric Supplement)

U+1F300..U+1F64F

U+1F680..U+1F6F3

U+1F90D..U+1F9FF

U+2600..U+263F

U+2643..U+266C

U+2670..U+2704

U+2707..U+2712

U+2719..U+2729

U+2731..U+27BF

-DF [partially updated RF and G]

Removed ★ and ☆ which seem to be getting a number of legitimate uses associated with stylized music titles in Asian languages (e.g. Japanese) but don't seem to be used much for vandalism.  -DF

Removed ✓✔✕✖✗✘ which get used in some tables, added an exception for content explicitly wrapped as unicode / nihongo, which vandals generally don't do.  -DF

Removed ♭♮♯ which are on the toolbar and occasionally used for music articles.  -DF

Change to disallow.  -DF

rm ♀,♁,♂ per false pos. RF 20150803

added an exemption for Principia Mathematica which uses ✸. 20150805

"unicode" doesn't have to be a template, any time the word "unicode" appears is likely to be FP. - KoH 20170113

  Removed white shadowed starb (unicode  2730) RF 20171020

Exclude GF IP editor. RF 20180724

GF IP hasn't edited in a few months, add 🅱️ emoji. -Galo 2019-01-24

Exclude emojis in refs; emojis legitimately appear far too often in them - mainly in titles which may be autogenerated by VE and so the editor may not even notice that they are adding emojis. No need for rcount stuff - if removed_lines has emojis, it is quite possible that there are more non-vandal use of emojis in the same lines. -Galo 2019-02-01

Include all of Enclosed Alphanumeric Supplement. -G 2019-03-05

Pages with exemptions

:Updated 20190331 ~Xaos

Add most of https://www.unicode.org/charts/nameslist/n_1F900.html - emojis, see also Template:Emoji_(Unicode_block) - per FNs ([[Special:PermaLink/903263535#False_negatives]]). Also use equals_to_any instead of regex to check page ids for exclusion. -G 2019-06-04

Use \x{} syntax instead of raw unicode in the pattern. More readable, less error-prone, and there's no need to keep the notes in sync anymore. (They were already wrong.) Setting to tag-only for a little while for safety. --Suffusion of Yellow 22:44 30 Oct 2019

Exclude U+26AD (Marriage symbol); used on some family tree pages. --Suffusion of Yellow 00:24 31 Oct 2019

Exempt astronomy articles which need to use weird symbols like [[Solar mass]]. - KoH 2020-04-16

Add letters (only) from [[Enclosed Alphanumerics]] block. Tested in filter 1013. --Suffusion of Yellow 20:25 2 Jun 2021

Add word boundary to "astro", was matching on "Castro", "disastrous", etc. and causing false negatives --Suffusion of Yellow 20:28 2 Jun 2021

Exclude U+2666 (Black diamond suit) per FPs. --Suffusion of Yellow 22:36 26 Feb 2022

Adding 1F595. --Oshwah 5/1/2022
