This document covers the following topics:

Inserting non-English characters (ü ç ñ á ß, etc.) into a document.
Using multi-lingual capabilities (spell checker, thesaurus, etc.) in WordPerfect and Microsoft Word.

Inserting non-English characters (ü ç ñ á ß, etc.) into a document:
Inserting non-English characters into a document can be done by switching keyboard formats, by using Symbols in WordPerfect, or by using Character Map when using most Windows programs:
Switching Keyboard Formats:
Adjusting to a different keyboard language format is tricky, but it is the fastest way to access non-English characters in the long run. Keyboard formats can be switched by clicking on the keyboard language icon in the system tray in the lower right corner (circled in red). A menu listing the available keyboard formats will then appear. Select the desired keyboard language format.

The keyboard will then react as if it were in that language format. It will take practice to adjust to the format, if you are not used to using it. Reverse the procedure to switch back to English or to another language.
Symbols in WordPerfect:
When using WordPerfect, insert non-English characters by using Symbols. First move the cursor to the point in the document where the character is to be placed. Press Ctrl-W or select Insert > Symbol... from the menu bar. Then select the desired set. Double-click on the symbol to insert.

Character Map:
Character Map will allow you to paste any character as text into the document of a Windows program. Character Map is accessed by clicking on the start button in the lower left corner and then selecting Programs > Accessories > Character Map. First select the font that you will be working with. Then double-click on the character to be copied. Then select Copy.

Now return to the application where you would like to place the character. Be sure the cursor is in the location where you would like the character inserted. Then select Edit > Paste from the menu bar.

Using multi-lingual capabilities (spell checker, thesaurus, etc.)

WordPerfect

Microsoft Word.

Using WordPerfect's multi-lingual capabilities:
Knowing how to use WordPerfect's multi-lingual capabilities will allow you to spell check documents and also use the thesaurus in various languages.
To switch languages in WordPerfect, first position the cursor. The language settings will be changed for all of the document following the cursor. Select Tools > Language... from the menu bar. Then select the desired language.

If a document contains multiple languages, the language settings can be changed for each portion of text. First highlight the portion of text to be changed with the mouse. Then select Tools > Language... from the menu bar. Then select the desired language.

Once the language settings have been selected, the document can be properly spell checked. As WordPerfect encounters each language setting, the spell checker will automatically switch to that language.

Using Microsoft Word's multi-lingual capabilities:
To switch languages in Word, you will follow a process similar to that of WordPerfect. First, select the desired text. Then click Tools > Language > Set Language... Then select the desired language.
Just as in WordPerfect, you can have multiple languages in one document and Word will make the adjustments accordingly. However, only English, Spanish and French language tools are installed by default.
