How are Engrish/language barrier jokes dealt with in English dubs? There are some scenes in anime which show language barriers. For instance, one character speaks fluent English (because he/she has lived in a foreign country and has recently came to Japan) and another character(who is listening) is having a difficult time comprehending it. Some examples include Kiniro Mosaic (the anime is all about characters dealing language barriers), Azumanga Daioh etc. Now, how are these scenes dubbed in English? How do dubbers deals with these scenes? Are these scenes even dubbed? Or is the plot changed conveniently to match with the English dub?
Consider the following scenes:

The famous coffee scene in Kiniro Mosaic.
&quot;oh my gah&quot; scene in Azumanga Daioh
The &quot;no speaking English&quot; scene in Nichijou

How are these scenes dubbed in English?
The answer for Kiniro Mosaic is that ... the anime was never dubbed in English so they never had to worry about it.

More generally, it will depend a lot on the way the dubbing company chooses to localise it, which in turn often depends on the expected audience for the dub. In the case of Azumanga Daioh, for example, the English jokes were made into Spanish ones instead, capturing the same general idea of the joke.

Another example I wanted to dig up was Excel Saga, which has a couple of scenes with notoriously (and, given the nature of the show, almost certainly deliberately) bad English (e.g. "General, she got it!" which in the English subtitles of the Japanese subtitles is translated as "General, I think she understands what we're saying"). The ADV dub treated these in different ways in different scenes, which feels quite on-brand for the show - some of the lines were just dubbed with proper English, losing that part of the joke; other lines were switched into another language, like in Azumanga; one line is given a complete non-sequitur joke that actually refers back to the Japanese version; and one section, where the joke in the original is that the English doesn't even relate to the scene (and is mostly made up of clichéd sentences that Japanese speakers might recognise, like "Give me chocolate") is left in its original form with the original voice actors.
