# Decode MDB Strange Chars

A workaround to solve the character decoding problem of .mdb files (MS Access)

NPM link: [@el3um4s/decode-mdb-strange-chars](https://www.npmjs.com/package/@el3um4s/decode-mdb-strange-chars)

### Install and use the package

To use the package in a project:

```bash

npm i @el3um4s/decode-mdb-strange-chars

```

and then in a file:

```ts

import {

  decodeString,

  decodeVBSBuffer,

} from "@el3um4s/decode-mdb-strange-chars";

import { vbs } from "./sql";

const file = path.resolve("./src/__tests__/test.mdb");

const sqlString = `SELECT * FROM [test] WHERE [ordine]=${ordine};`;

const result = await runVbsBuffer({

  vbs,

  args: [file, `"${sqlString}"`, type],

});

const decoded = decodeVBSBuffer(result);

console.log(decoded);

// {"result":[{"ordine": "157","carattere": "à","utf-8 bytes": "c3 a0","descrizione": "LATIN SMALL LETTER A WITH GRAVE","codice win": "85"}]}

const codeAccess = "85";

const decodedChar = decodeString(codeAccess);

console.log(decodedChar);

// à

```

### API

- `decodeString(text: string): string` decode a string of hex code to a string of characters

- `decodeVBSBuffer(buffer: string[]): string` decode a buffer of hex code to a string of characters

### Acknowledgments

My problem is reading mdb files even when there are strange characters. This package is meant for [node-mdb](https://github.com/el3um4s/node-mdb). It serves as an intermediate step to convert the characters obtained from [run-vbs](https://github.com/el3um4s/run-vbs). I keep it as a separate package so that I can use it in other projects as well. And, above all, to be able to test it independently and, at the same time, keep the _node-mdb_ code clean.
