stylistic changes to the id

the initial and current state of this property differs from how I preposed it two weeks ago without any consensus. according to the examples section, id's should be altered from how they appear on Discogs: + shall be replaced with (space). That unfortunately makes the id useless for me. The formatter URL (P1630) still resolves to the correct entity on Discogs. However it does not work the other way around. When I extract the id from using URL match pattern (P8966) I get:

https://www.discogs.com/style/rhythm+&+blues → URL match pattern (P8966) → rhythm+&+blues

Which unfortunately does not resolve to the corresponding item rhythm and blues (Q45981):

SELECT ?rnb ?rnbLabel WHERE {
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
  ?rnb wdt:P9219 "rhythm+&+blues".
}
LIMIT 1

Try it!

So I hereby propose the id should not be changed from how it appears on Discogs and in accordance to the undisputed consensus in the property proposal. --Shisma (talk) 09:12, 28 February 2021 (UTC)

Format should allow for more characters

• It appears that dots are permissible in style IDs. For example, https://www.discogs.com/style/p.funk is the correct URL for P-Funk (Q577080), although there is also http://reference.discogs.com/style/P-Funk (which redirects to https://reference.discogs.com/style/p-funk then).
• Same for apostrophes, e.g. min'yō (Q901610) → https://www.discogs.com/style/min%27y%C5%8D
• Further, Yellow music (Q1499262) and funaná (Q3090876) reference valid IDs with special characters not covered by the current pattern.
