   - Not possible to SELECT BLOB column values directly. It is recommended to use built-in HEX function to retrieve BLOB column values, which should work consistently across all platform implementations as well as (WebKit) Web SQL. Non-standard BASE64 function to SELECT BLOB column values 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 terms).
   - Windows platform version uses `UTF-16le` internal database encoding while the other platform versions use `UTF-8` internal encoding.

 - Boolean `true` and `false` values are handled by converting them to the "true" and "false" TEXT string values, same as WebKit Web SQL on Android and iOS. This does not seem to be 100% correct as discussed in: [litehelpers/Cordova-sqlite-storage#545](https://github.com/litehelpers/Cordova-sqlite-storage/issues/545)
 - A number of uncategorized errors such as CREATE VIRTUAL TABLE USING bogus module are reported with error code 5 (SQLError.SYNTAX_ERR) on Android/iOS/macOS by both (WebKit) Web SQL and this plugin.
-- Issues with error code on Windows as well as Android with the `androidDatabaseImplementation: 2` setting described below.
+- Error is reported with error code of `0` on Windows as well as Android with the `androidDatabaseImplementation: 2` setting.
 - In case of an issue that causes an API function to throw an exception (Android/iOS WebKit) Web SQL includes includes a code member with value of 0 (SQLError.UNKNOWN_ERR) in the exception while the plugin includes no such code member.
 - This plugin supports some non-standard features as documented below.
 - Results of SELECT with BLOB data such as `SELECT LOWER(X'40414243') AS myresult`, `SELECT X'40414243' AS myresult`, or reading data stored by `INSERT INTO MyTable VALUES (X'40414243')` are not consistent on Android in case the built-in Android database is used (using the `androidDatabaseImplementation: 2` setting in `window.sqlitePlugin.openDatabase`) or Windows. (These work with Android/iOS WebKit Web SQL and have been supported by SQLite for a number of years.)

 - A stability issue was reported on the iOS platform version when in use together with [SockJS](http://sockjs.org/) client such as [pusher-js](https://github.com/pusher/pusher-js) at the same time (see [litehelpers/Cordova-sqlite-storage#196](https://github.com/litehelpers/Cordova-sqlite-storage/issues/196)). The workaround is to call sqlite functions and [SockJS](http://sockjs.org/) client functions in separate ticks (using setTimeout with 0 timeout).

 - It is NOT possible to open multiple databases with the same name but in different locations (iOS/macOS platform version).
