I have an issue with escape ASCII characters that breaks XML and other treatments I could make on tweets, that are rejected when I try to analyze them.
For example, the following request https://api.twitter.com/1.1/users/show.json?user_id=467851549 is answering “name”: “\u0015кαу.❀” and the “\u0015” (which is the negative axknowledge character http://www.fileformat.info/info/unicode/char/15/index.htm) breaks the treatments I could try on the user and on his tweets.
If you take a look at twitter web interface, you will see that this character is not printed (https://twitter.com/__Kaaaylaaa)
Is it possible to disallow this type of characters (control characters), at least from names/bio/description? and if possible from tweets?
