When testing my code that uses a routine that checks for chars to show using an ASCII value routine, my program should drop control chars but keep chars that may be entered by the user. It seems that while the ASCII value routine is called "ascii", it does not just return ascii values: giving it a char of ƒ returns 402.
For example have found this web site but it doesn't have ƒ 402 that I can see.
Need to know whether there are other ascii codes above 402 that I need to test my code with. The character set used internally by the software that 'ascii' is written in uses UCS2. The web site found doesn't mention USC2.
There are probably many interpretations ouf »Control Character« out there, but I'll assume you mean C0 and C1 control characters (includes references to the relevant Unicode Standards).
The commonly used 32-bit integer representation of Unicode characters in general is the codepoint notation: »U+« followed by a at least 4 digit positive hex number, which you will find near mentions of characters, e.g. as in »U+007F (delete)«. The result of your »ASCII value« routine will probably be this number without the »U+«;
UCS-2 is a specific encoding for Unicode characters, which you probably won't need to care about directly), and is equivalent to Unicode codepoints for all characters within the the range of the BMP only.
