Working with text
and fonts when creating PDF files
You can determine how
the text in your PDF file outputs by setting text and font options.
You can choose how
text is encoded in a PDF file to accommodate the type of text your file contains
and specific output requirements. For example, if you are creating a
multilingual document that includes, English, German, and Japanese, choose the
Unicode encoding option. Unicode is designed to support text characters from a
wide range of languages, including Chinese, Japanese, and Korean. If you are
creating an English or German document, ASCII encoding is commonly used. The
default setting should work in most cases, but the type of software or hardware
you are using to output your files can also influence which encoding option you
need. For example, older raster image processors (RIP) may not support type that
is defined in a Unicode format.
You can embed fonts
in a PDF file, including PostScript base 14 fonts. Embedding increases the file
size but makes a PDF file more portable, since the fonts do not have to reside
on other systems. When you embed base 14 fonts, the fonts are added to your PDF
file, thus eliminating font variances on different systems. The base 14 fonts
are resident on all PostScript devices.
You can also convert
TrueType fonts to Type 1 fonts, which can increase file size if there are many
fonts in a file. When you convert fonts, you can reduce file size by subsetting
Type 1 fonts if you use only a smaller number of characters (for example,
English characters A to E). You can also include a percentage of fonts used. For
example, you can create a subset of 50 percent of fonts. If the number of
characters used in the document exceeds 50 percent, the whole set of characters
is embedded. If the number of characters used in the document is less than 50
percent, only the characters used are embedded.
You can also
eliminate font variances on different computers by exporting text as curves. For
example, if you are using unusual text characters, you can export the text as
curves. Exporting text as curves increases the complexity of the file and can
increase file size. For general document publication, embed fonts in a document
rather than convert text to curves.

To specify text encoding for a PDF file
1. Click File
 Publish to PDF.
2. Click Settings.
3. Click the Objects tab.
4. In the Text and fonts area, choose one of the following options:
• ASCII — American Standard Code for Information Interchange. This
format is generally more compatible with Latin-based languages than
Unicode, but is not fully
multilingual
• Unicode — a more recent encoding format that is fully
multilingual. This format supports languages such as Chinese,
Japanese, and Korean, but may not be
supported by some raster image processors
or viewers.

To embed fonts in a PDF
file
1. Click File
Publish to PDF.
2. Click Settings.
3. Click the Objects
tab.
4. Enable the Embed
fonts in document check box.
If you
want to install the basic fonts to your PDF file, enable the
Embed base 14 fonts check box.
• Enabling
the Embed base 14 fonts check box increases file size, and,
therefore, it is not recommended for publishing to the World Wide
Web.

To convert TrueType fonts to Type 1
fonts
1. Click File
Publish to PDF.
2. Click Settings.
3. Click the Objects tab.
4. Enable the Convert TrueType to Type 1 check
box.
If you want to reduce file size,
you can create a subset of Type 1 fonts by enabling the Subset fonts
check box and typing a percentage of fonts used in the Under%
of charset box.
• If you create a subset of Type 1 fonts, you should not edit or
correct the PDF file using Adobe Acrobat, since the characters you add when
editing may not be present
in the file
