 - SQL error messages reported by Windows platform version are not consistent with Android/iOS/macOS platform versions.
 - UNICODE `\u2028` (line separator) and `\u2029` (paragraph separator) characters are currently not supported and known to be broken on iOS, macOS, and Android platform versions due to JSON issues reported in [Cordova bug CB-9435](https://issues.apache.org/jira/browse/CB-9435) and [cordova/cordova-discuss#57](https://github.com/cordova/cordova-discuss/issues/57). This is fixed with a workaround for iOS/macOS in: [litehelpers / Cordova-sqlite-evplus-legacy-free](https://github.com/litehelpers/Cordova-sqlite-evplus-legacy-free) and [litehelpers / Cordova-sqlite-evplus-legacy-attach-detach-free](https://github.com/litehelpers/Cordova-sqlite-evplus-legacy-attach-detach-free) (GPL or special commercial license terms) as well as [litehelpers / cordova-sqlite-evmax-ext-workers-legacy-build-free](https://github.com/litehelpers/cordova-sqlite-evmax-ext-workers-legacy-build-free) (GPL or premium commercial license terms).
 - SELECT BLOB column value type is not supported consistently across all platforms (not supported on Windows). It is recommended to use the built-in HEX function to SELECT BLOB column data in hexadecimal format, working consistently across all platforms. As an alternative: SELECT BLOB in Base64 format is supported by [litehelpers / cordova-sqlite-ext](https://github.com/litehelpers/cordova-sqlite-ext) (permissive license terms) and [litehelpers / Cordova-sqlite-evcore-extbuild-free](https://github.com/litehelpers/Cordova-sqlite-evcore-extbuild-free) (GPL or commercial license options).
-- Database files with certain multi-byte UTF-8 characters are not tested and not expected to work consistently across all platform implementations.
+- Database files with certain multi-byte UTF-8 characters SUCH AS XXX are not tested and not expected to work consistently across all platform implementations.
 - Truncation in case of UNICODE `\u0000` (same as `\0`) character on Android (default Android-sqlite-connector database implementation) and Windows.
 - Case-insensitive matching and other string manipulations on Unicode characters, which is provided by optional ICU integration in the sqlite source and working with recent versions of Android, is not supported for any target platforms.
 - The iOS/macOS platform version uses a thread pool but with only one thread working at a time due to "synchronized" database access.
