FYI, Processing Multilingual Invoices.pdf, which at the time of this writing is an internal document, refers to this topic by name. I think INI Help does, too.
The character set that the system uses when extracting data from invoices is specified in the settings in the dialog.
You can edit invoice-related character sets by removing or adding some characters. However, note that it does not work to add characters from one language's alphabet to the character set of another. For example, adding the Danish characters æ and ø to the Swedish character set does not result in æ and ø being extracted on Swedish invoices. To extract characters that are specific to the Danish alphabet, you must use a Danish country profile and a Danish character set.
You can also create your own character sets. The number of character sets is limited to 30.
Important:Read warning before proceeding!
Using the Invoice Manager module, select > . The dialog is displayed.
In the list box, choose the character set you want to edit.
The group box shows the current characters in that character set. Make your changes there. (Each part of the character set, except , corresponds to options in the group box in the settings for the field profile.)
All characters in the character set, including any characters you add, must be present in the code page that is selected in the box. No checking is performed. You must be sure that the characters you add are present.
When you are finished, click . The dialog closes. Changes are saved in Ehcharset.ini automatically.
Recommended: Before you add your own character set, contact ReadSoft about how to do so. This is because internal adjustments may be necessary to accommodate your character set.
Use this procedure (after arranging the necessary changes with ReadSoft):
Using Manager, select Settings > Character sets. The Character sets dialog is displayed.
Click Save as. In the dialog that is displayed, type a name for the new character set.
In the Specification group box, change the character set. (Each part of the character set, except Code page, corresponds to options in the Format group box in the General settings for the field profile.)
All characters in the character set, including any characters you add, must be present in the code page that is selected in the Code page box. No checking is performed. You must be sure that the characters you add are present.
When you are finished, click OK. Changes are saved in Ehcharset.ini automatically.
