Use a substring function that doesn’t assume 1 byte = 1 character. Unicode has been around long enough that everything should be prepared for it. mb_substr 3 solved how to remove this char “�” from string output [closed]
You cannot just change the type of an array. If the first array is a char array, you need to create a new array that would hold integers. Then index by index you need to convert the character from the first array to an integer and then store it in your new array. int intArray[10]; … Read more
Let’s say I have an array of characters (a string ) and I want to count how many time each character appears. However there should be no if solved Let’s say I have an array of characters (a string ) and I want to count how many time each character appears. However there should be … Read more
Use UTF-8 instead. It’s understood by every self-respected client side and server side operating system platform. It’s also considered the standard character encoding these days. Tomcat still defaults to the old ISO 8859-1 charset as to decoding GET request parameters and to the server platform default encoding as to decoding POST request parameters. To set … Read more
This seem to be an encoding issue, check the encoding of your source file. You should be able to change it with your IDE.

I gave a unsatisfying answer, thanks to @OlegEstekhin for pointing that out. As noone else answered yet, and a solution is not a two-liner, here it goes. Make a wrapping InputStream that throws away escape sequences. I have used a PushbackInputStream, where a partial sequence skipped, may still be pushed back for reading first. Here … Read more
C0 is an invalid start byte for a two-byte UTF-8 sequence, but if a bad UTF-8 decoder accepts it C0 B1 would be interpreted as ASCII 31h (the character 1). Quoting Wikipedia: …(C0 and C1) could only be used for an invalid “overlong encoding” of ASCII characters (i.e., trying to encode a 7-bit ASCII value … Read more
I found the answer! It’s inspired by this answer $title = “Hunting, Tactical & Outdoor Optics eCommerce Store ΓÇô $595,000 ΓÇö SOLD”; $title = str_replace(html_entity_decode(‘–’, ENT_COMPAT, ‘UTF-8’), ‘-‘, $title); $title = str_replace(html_entity_decode(‘—’, ENT_COMPAT, ‘UTF-8’), ‘-‘, $title); Replacing the character right away won’t work. html_entity_decode is definitely needed. solved PHP – Convert ΓÇô to dash
Yes on all four. To clarify, the term “pair” in UTF-16 refers to two UTF-16 code units, the first in the range D800-DBFF, the second in DC00-DFFF. A code unit is 16-bits (2 bytes), typically written as an unsigned integer in hexadecimal (0x000A). The order of the bytes (0x00 0x0A or 0x0A 0x00) is specified … Read more
In C, characters are represented internally using ascii. Characters are just numeric types, so adding them just adds the ascii* values. (Google ASCII for more info on this.) In ascii, ‘=’ is 61, so ‘=’ + ‘=’ is the same as 61 + 61, or 122, which is what you’re getting. If you were hoping … Read more
