Issue

  • The following error is thrown when certain characters are included in the registration of web content, notice portlets, etc.
Incorrect string value: '\xF3\xA0\x84\x80\xE9\x87...' for column 'content' at row 1

Environment

  • Liferay Portal 6.2, Liferay DXP 7.0, Liferay DXP 7.1, Liferay DXP 7.2

Resolution

  • If you are using MySQL and the charset setting is UTF-8, an error may be thrown
  • This problem occurs because MySQL UTF-8 can store up to 3 bytes and does not support characters with more than 3 bytes.
  • You need to set the charset to utf8mb4 or use a database other than MySQL
  • If you use utf8mb4, adjust the database-oriented settings defined in portal-ext.properties as follows
jdbc.default.url = jdbc: mysql: // localhost / lportal? dontTrackOpenResources = true&holdResultsOpenOverStatementClose = true&useFastDateParsing = false
