 ### Character Encoding
 
-To ensure the integrity of your data you need to select the correct character encoding for your dataset. MarcEdit does not automatically detect character encoding, however, UTF8 is set as the default encoding scheme. You can update the encoding scheme when using the MarcBreaker, or you can update the default in Preferences → MarEditor → Default Encoding. For more information on character encoding and translating from one encoding to another, see [The MarcEdit Field Guide](https://marcedit.reeset.net/learning_marcedit/9-2/dealing-with-character-encodings-in-marcedit/)

 **Note:** When you break a .mrc file and create a new .mrk file for editing in the MarcEditor, you are making a copy of your data in a new file format. As a result, any edits you make to the .mrk file in the MarcEditor will not automatically be reflected in the original .mrc file. We will cover saving and compiling (using the MarcMaker) to create an updated .mrc file in an upcoming lesson.

 ### MARC syntax in the MarcEditor
 
-Understanding the layout of MARC data in the MarcEditor is key to using the program's tools successfully. For instance, in some tools it is important to specify a field's indicators directly preceeding the first subfield. Throughout this workshop we will highlight how different tools rely on this syntax to apply edits.

-- The MARC Tools Icon allow you to convert data from one file format to another
-- The MarcEditor works with a MarcEdit specific mnemonic format of MARC records (.mrk)
-- It is necessary to break a MARC binary file to work with that MARC data in the MarcEditor. The extension of these easily readable MARC files are .mrk rather than the binary extension of .mrc
