## set_font ##

```python
fpdf.set_font(family, style = '', size = 0)
```

### Description ###

Sets the font used to print character strings. It is mandatory to call this 
method at least once before printing text or the resulting document would not 
be valid.

The font can be either a standard one or a font added via the 
[add_font](add_font.md) method. 

Default encoding is not specified, but all text writing methods accept only
unicode for external fonts and one byte encoding for standard.

Standard fonts use `Latin-1` encoding by default, but Windows 
encoding `cp1252` (Western Europe) can be used with 
[set_doc_option](set_doc_option.md) ("core_fonts_encoding", encoding).

The method can be called before the first page is created and the font is 
retained from page to page.

If you just wish to change the current font size, it is simpler to call 
[set_font_size](set_font_size.md).

**Note**: the font metric files must be accessible. They are searched 
successively in:

 * The directory defined by the FPDF\_FONTPATH constant (if this constant is 
   defined)
 * The font directory located in the directory containing fpdf.py (if it 
   exists)

The directories accessible through include()
Example defining FPDF_FONTPATH (note the mandatory trailing slash):
define("FPDF_FONTPATH","/home/www/font/");
require("fpdf.php");
If the file corresponding to the requested font is not found, the error "Could 
not include font metric file" is issued.


### Parameters ###

family:
> Font family. It can be either a name defined by [add_font](add_font.md) or 
  one of the standard families (case insensitive):
>>  * Courier (fixed-width)
>>  * Helvetica or Arial (synonymous; sans serif)
>>  * Times (serif)
>>  * Symbol (symbolic)
>>  * ZapfDingbats (symbolic)
> 
> It is also possible to pass an empty string. In that case, the current 
  family is retained.

style:
> Font style. Possible values are (case insensitive):
>>  * empty string: regular
>>  * B: bold
>>  * I: italic
>>  * U: underline
> 
> or any combination. The default value is regular. Bold and italic styles do 
  not apply to Symbol and ZapfDingbats.

size:
> Font size in points.
> The default value is the current size. If no size has been specified since 
  the beginning of the document, the value taken is 12.

### Example ###

```python
# Times regular 12
pdf.set_font('Times')
# Arial bold 14
pdf.set_font('Arial', 'B', 14)
# Removes bold
pdf.set_font('')
# Times bold, italic and underlined 14
pdf.set_font('Times', 'BIU')
```
