The answer to this question depends on the machine translation platform being used. Language Studio™ handles complex formatting embedded in documents such as Microsoft Word, PowerPoint or standard XML interchange formats such as XLIFF or TMX.
Many machine translation
tools and platforms cannot handle complex formatting. There
is a common
misconception that RBMT can handle formatting, but SMT
cannot. This is totally
false, but this myth continues to be perpetrated through
the market by parties with a vested interest in legacy RBMT tools that
have not moved to more
advanced and modern platforms.
Open source Moses does
not handle complex formatting. Anyone adopting this platform
needs to write their own
software to manage complex formatting for
manually reinsert the
formatting after the translation is complete.
