Important tip about word documents

Checking a document that a client of mine had problems to process in SDL Trados Studio I came to learn this:

When Word calculates line length and wraps text to the next line, it tries to break the line at a space or a hyphen--a dash. Sometimes, however, you may not want Word to break a line at a dash. For instance, dashes are used in telephone numbers, and you might not want a line to break in the middle of a telephone number. The answer is to use non-breaking hyphens instead of regular dashes when you don't want Word to break a line at the hyphen. To do this, hold down the Ctrl and Shift keys as you type the dash (this is the same as typing Ctrl and an underscore). Word will then not break the line at that point.

This hyphens are shown in SDL Trados as tags and can become very annoying so we decided to remove them with search replace before processing, as this will not show when translated into Spanish.
