#  `update_info_utf8`

Update PDF metadata from `dump_data_utf8` instructions
## Usage
> pdftl `<input>` `update_info_utf8` `<metadata>` `output` `<filename>`

## Details
Updates the document-level metadata and structural
information of the input PDF by reading from a specified
metadata file (or stdin).

This operation is the direct counterpart to
`dump_data_utf8`. It is identical to `update_info`, except
it assumes the input file contains raw UTF-8 strings that
have **not** been XML-escaped.

Use this operation if your metadata source file was created
by `dump_data_utf8` or if you have manually created a
metadata file that contains raw, unescaped UTF-8 characters.

For a complete description of the input format this command
expects, see the help for `dump_data`.
## Examples

> Update utf-8 metadata according to meta.txt
```
pdftl in.pdf update_info_utf8 meta.txt output out.pdf
```


**Tags**: info, metadata
