For example, the cp1252 charset maps code points from 0 though 255, but it has only 251 entries: 0x81, 0x8D, 0x8F, 0x90 and 0x9D code points are not assigned. Contents Special symbols. This would confuse the compiler because it expects all String literals to begin and end with a quotation mark. There are special cases for strings where all code points are below 128, 256, or 65536; otherwise, code points must If you ask for unicode, you will always get unicode or an exception is raised.

This is unfortunate, as in many cases it can be useful to specify Unicode codepoints by number, rather than using the codepoint directly. You can pass to it non-encoded data and it should be able to process it properly (you will need to make sure that you decode the output that is returned). The major problem is that there are more than 256 of them. The escape() function was deprecated in JavaScript version 1. They are extracted from open source Python projects. ChatterBot is able to handle unicode values correctly. Such escape sequences are also implemented directly by the regular-expression parser so that Unicode escapes can be used in expressions that are read from files or from the keyboard.

"Normal" is a matter of what is commonly used The Unicode Consortium is a non-profit, 501(c)(3) organization founded to develop, extend and promote use of the Unicode Standard and related globalization standards which specify the representation of text in modern software products and other standards. Code page is the name that SAP uses instead of character encoding. 3. Unicode has no code points allocated for any controls other than the C0 and C1 ones. The "bad" part is that according to what I was told/seen the tool doesn't play well with special characters (probably uses some incorrect encoding) and requires that these characters are transferred to the equivalent unicode escape code. com wrote: > As I saw, I could solve the problem by changing line 4 to (small letter > "r" before string: > ROOTDIR = r'C:\Users\zoran' > > but that is not an option for me because I am using configparser in order > to read the ROOTDIR from underlying cfg file. Unicode escapes are used to represent Unicode symbols with only ASCII characters. Here, \U starts an eight-character Unicode escape, such as '\U00014321`.

Next example shows how you can get the error: import json json_data=open("C:\Users\test. Character encodings map characters to byte representations. In Scala, unicode escape sequences are processed not only inside character or string literals. Code pages have a 4-digit number instead of a character name. The value of a UTF-8 character literal containing a single character, escape sequence, or universal character name has a value equal to its ISO 10646 code point value if it can be represented by a single UTF-8 code unit (corresponding to the C0 Controls and Basic Latin Unicode block).
