Length of translation for API

[Yuiry Saprykin]

What is the maximum length of text for translation may be given to
Google's API?
I read rules, there is mentioned 5000 charcters, but in fact when the
text is larger then 350 characters google.language.translate fails
with no response at all! Whats up?

You can send source strings of up to 5,000 characters, but there are a
few provisos that are sometimes lost.

First, you can only send the 5,000 characters via the POST method. In
other words, you can't use the AJAX side of the API. If you want to do
the translation in a browser, you will have to (a) write your own
client-side Javascript API utilizing XMLHttpRequest and (b) write your
own server-side proxy script which will accept the request from the
browser, relay it to Google and get the response back, and then return
the response to the client.

Second, if you do use the default AJAX interface, you are limited to
submitting requests via the GET method, and Google has placed an appr.
2,000-character length limit on urls. If a url is longer than that,
Google's servers will just reject it. It should be noted that, within
this 2,000-character limit, you must also count the path and the rest
of the query string as well. So your 2,000 characters quickly dwindles
to more like 1,250 or so.

And finally, all of these limits are AFTER the string has been uri
encoded. In other words, every space becomes a %20, every quotation
mark a %22, and every non-Latin character its own uri-encoded entity.
For non-Latin languages (e.g., Chinese, Japanese, Urdu, Russian,
etc.), this can very quickly add up so that you run out of characters
pretty fast.

See also comment #13
at the bottom of this page:

As noted there, the 2K limit (which "affects many services") is
"the safe approach", given Internet Explorer's limitation on URL
length.
