std::wstring VS std::string

I am not able to understand the differences between std::string and std::wstring. I know wstring supports wide characters such as Unicode characters. I have got the following questions: When should I use std::wstring over std::string? Can std::string hold the entire ASCII character set, including the special characters? Is std::wstring supported by all popular C++ compilers? … Read more

Python – ‘ascii’ codec can’t decode byte

encode converts a unicode object to a string object. But here you have invoked it on a string object (because you don’t have the u). So python has to convert the string to a unicode object first. So it does the equivalent of But the decode fails because the string isn’t valid ascii. That’s why you get a complaint about not being able to … Read more

“Unicode Error “unicodeescape” codec can’t decode bytes… Cannot open text files in Python 3

The problem is with the string Here, \U in “C:\Users… starts an eight-character Unicode escape, such as \U00014321. In your code, the escape is followed by the character ‘s’, which is invalid. You either need to duplicate all backslashes: Or prefix the string with r (to produce a raw string):

What’s up with these Unicode combining characters and how can we filter them?

What’s up with these unicode characters? That’s a character with a series of combining characters. Because the combining characters in question want to go above the base character, they stack up (literally). For instance, the case of ก้้้้้้้้้้้้้้้้้้้้ …it’s an ก (Thai character ko kai) (U+0E01) followed by 20 copies of the Thai combining character mai tho (U+0E49). How … Read more

UnicodeDecodeError: ‘charmap’ codec can’t decode byte X in position Y: character maps to

The file in question is not using the CP1252 encoding. It’s using another encoding. Which one you have to figure out yourself. Common ones are Latin-1 and UTF-8. Since 0x90 doesn’t actually mean anything in Latin-1, UTF-8 (where 0x90 is a continuation byte) is more likely. You specify the encoding when you open the file:
