I’ve notice, when trying use a mobile symbol UTF-8, that after saving the description filed was empty. Tried several times.
Symbol – http://www.fileformat.info/info/unicode/char/1f4f1/browsertest.htm
WP – 4.9.4
FV Simpler SEO 1.7

Hello Alex,
I believe this is related to your database. I didn’t had any issues with this, the ? symbol was accepted. The database where I tested this was using utf8mb4_unicode_ci collation. Perhaps your wp_postmeta table is using something else.
Thanks,
Martin
server collation utf8mb4_unicode_ci
database collation utf8_general_ci
tables utf8_general_ci
Hello Alex,
utf8mb4_unicode_ci is required to store these symbols. It’s strange that you are using just utf8_general_ci, as WordPress 4.2 was updating the tables to utf8mb4_unicode_ci automatically – although with some difficulties, as explained in our article – WordPress 4.2 Database Update Difficulties
I’m not sure how to force the update, but you can play with the “db_version” database option and see if setting it below 31533 will force WordPress to re-try that update.
Actually it seems like some suggestions can be found here: Switch WordPress from utf8 to utf8mb4 retrospectively
Thanks,
Martin
You don’t believe it but I’ve recently read it))
According article this function rule conversion from utf8 to utf8mb4:
maybe_convert_table_to_utf8mb4( $table )But instead I use a direct mysql command:
ALTER TABLE $table CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_cifor certain tables.
More over, I’ve somewhere read a point about latest utf8 support that is:
utf8mb4_unicode_520_ciand now I’m thinking about converting to this type of collation
Hello Alex,
I don’t know all the details about it, but once it’s finished you shouldn’t be having any issues with the characters like the above.
However are you sure it makes sense to use such symbol for SEO reasons?
Thanks,
Martin
Hello Martin.
what do you mean it’s not safe or what?
I’ve try to stylizes a SERP in Google and maybe a link preview in another systems
Hello Alex,
I mean that Google might remove such symbol from SERP. And even if it will come up, perhaps they will fix their systems to remove it as they might not like it. It’s not something you can search for by typing in a text.
Thanks,
Martin
Hello again Martin.
I need to get attention from searcher.
With those colorized symbols ⭐ ✅ ⌛ I have more chances get attention to it.
Maybe this isn’t best practice
