I have enabled comma as my decimal separator, which means that comma still acts normally and when pressing period it will be converted to a comma.

In the header I would like to make a period, so I insert a period and it looks like a period, however when I view the print preview, the period is converted to a comma.

How do I keep this from happening or is there a special period character that doesn't get converted to a comma?

Alternatively how can I make the header plain text, as this behavior doesn't occur in plain text mode?

Edit: Answering @SjoerdC.deVries questions:

  1. With header I mean the option you set with File > Printing Settings > Headers and Footers...
  2. The setting to change the decimal separator was found in Mathematica under Preferences > Appearance > Numbers > Formatting > Decimal point character
  3. The period is the normal period key, not one on the keypad, although I would think they act similar.

A few questions to make your question a little bit more specific: 1. With "header" you mean the page header which you set with File>Printing Settings>Headers and Footers...`? 2. The setting of comma as decimal separator did you do that within Mathematica's preferences (tab Appearance/Numbers) or on OS level or both? 3. Do you press the period on your numeric keypad or on the main keyboard? – Sjoerd C. de Vries Oct 23 '12 at 21:17

I cannot reproduce this. The period in the header remains as a period even though I changed the decimal separator to a comma. I'm using mma 8.04 on Mac OS 10.8. What's yours? – R. M. Oct 23 '12 at 22:06
If i recall correctly, on Windows the period on the keypad can be made to act as a decimal comma while the period on the main keyboard still produces a period. – Sjoerd C. de Vries Oct 23 '12 at 22:12
I'm using Mathematica 8.0 on Mac OS X 10.8.2 – Tyilo Oct 23 '12 at 22:12
