That's OK for me! Emoji is pronounced "ka" in Japanese and "ke" in Chinese. Roughly means: possible, appropriate, or permissible.
The Japanese 'Acceptable' button emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the symbols
category. Because the Japanese 'Acceptable' button emoji has been around for quite some time, it should display correctly in the majority of operating systems.
