Symbol font used when creating EPS files
The information in this document applies to:
MathType-generated EPS files that contain italic characters
from the Symbol font may not display correctly when printed or output to PDF.
Typical symptoms are using Courier instead of Symbol, or missing characters. This problem
can also occur when using bold or bold and italic Symbol characters.
A related issue may occur if you have the Windows TrueType
Symbol font installed, the EPS files will refer to it as SymbolMT for italic,
bold and bold/italic Symbol characters instead of Symbol. (The MT in SymbolMT
refers to MonoType, the company that created the font).
When generating EPS files MathType includes the PostScript
name for every font present in the equation. This includes variations like
italic and bold, which are referred to as separate fonts. As there is no italic
PostScript Symbol font, MathType has to handle these characters differently. If
you have the Windows TrueType Symbol font installed, MathType will use it
instead of Symbol, which looks perfectly fine but may not be what you expect.
If you remove the TrueType Symbol font and install a
PostScript Symbol font, MathType generates font names such as Symbol-Italic into
the EPS files, and these names aren't recognized when printing on a PostScript
printer or including the EPS file in a PDF.
MathType's Fonts folder contains a FontInfo.ini file which
can be used to extend MathType's knowledge of fonts, their encodings and
PostScript names. By adding the following information to this file MathType can
be instructed to use the proper names for italic and bold Symbol characters.
To edit your FontInfo.ini file, follow the steps below:
Navigate to C:\Program Files\MathType\Fonts
Make a backup copy of the FontInfo.ini file in case you need to revert back to it at any
Open the file FontInfo.ini using Notepad
Add the following to the end of this file:
Name = Symbol
Encoding = Symbol
PSName1 = P,Symbol
PSName2 = I,Symbol
PSName3 = B,Symbol
PSName4 = BI,Symbol
Note, if you have made any previous edits to this file, the
first line in this statement will need to reflect the next successive font
number appropriate to your file i.e [Font2], [Font3], [Font4] etc. For more
information read the comments in the FontInfo.ini file.
Also, we have anther TechNote that addresses similar problems that
you may experience when using MathType to generate PDF files.
