Warn about risks of hyphenation?

[pakal]

Hello, and thanks for this module,

I activated on my django-cms blog, however I noticed troubles later when copy/pasting text to other editors, or copyingh a partially obfuscated email address to my mail client. The hyphenation characters become dashes, or stay invisible but corrupt the processing later (eg. mail sending fails).

Maybe the readme should mention these few edge cases, for those that do not know the impacts of this hyphenation processing ?
