Depending on the level of abstraction you're living at - and that depends on the overall goal, performance constraints, environmental integration, OS / machine heterogeneity etc. - it may or may not be a problem.
It's easy to dismiss if you have all the time in the world and a deep stack of abstractions.
If you're doing deep packet analysis on UTF-16 text in a router, things may be different.
thanks, my question was right about the issues met by people living in another levels of abstractions.
i'm not a native english speaker and a newb to HN, so sorry that i put my sincere question so that it looked like arrogant statement 'there are no issues, what are you talking about, i even don't know what LE and BE mean'.
