问题 I have mainframe file in EBCDIC format and I want to convert those files into ASCII format.

问题 In my project I'm using huge set of short strings in ASCII 7-bit and have to process (store, compare, search etc) these strings with maximum performance. Basically, I build some Index array of uint64_t type and each element stores 9 characters of a word and use that index as Numeric element for any string comparison operation. Current implementation works fast, but may be it's possible to improve it a bit if you will.. This function converts up to 9 initial characters to uint64_t value - any

问题 just a simple question regarding calculations in IJVM as I couldn't find the solution in their documentation. Suppose we need to perform the following calculation: BIPUSH 0x32 // PUSH 2 BIPUSH 0x33 // PUSH 3 IADD // PUSH sum(2,3) OUT // output: "e" IADD ----> Pop two words from stack; push their sum I know the solution is likely straight forward, but for the life of me I can't recall on how to convert the addition/output to the actual digits. How to make it output "5" instead of this stupid

问题 I use the Levenshtein plugin for MySQL from: http://samjlevy.com/2011/03/MySQL-levenshtein-and-damerau-levenshtein-udfs/ I'm trying a query like: SELECT name FROM database WHERE levenshtein(name, 'testć') the problem is that levenshtein function doesnt handle accented characters. I need levenshtein to recognize characters like "C" and "Ć" (and others accented) as the same. So i decided to replace all of it in MySQL, but cant find any function for that. Like: SELECT name FROM database WHERE

问题 I have the following String passed from another application. 2�4�9� (2�4�9�) I would like to remove question mark ascii characters from the above string. How could I do this? 回答1: According to this Unicode code table, � (or \ufffd ) is the character �. You can remove this unicode character from your string with : str = str.replaceAll("�", ""); But you should really try to understand why they are there. 回答2: string.replaceAll("\u0000.*","").replaceAll("[^a-zA-Z0-9 ]", ""); will remove the

问题 I have a javascript/PHP script that does the following: Uses javascript to find text on a web-page. Transmits the text using jQuery AJAX to a PHP page. The PHP stores the text in a MySQL database. The trouble is, when I look at what has been stored in the database, some non-ASCII characters are corrupted. I have simplified the problem and printed out the character codes of each letter to investigate what is going on. For example: send over a single character, the pound sterling symbol. When I

问题 I know there are quite a few solutions for this problem but mine was peculiar in the sense that, I might get truncated utf16 data and yet have to make the best effort of dealing with conversions where decode and encode will fail with UnicodeDecodeError. So came up with the following code in python. Please let me know your comments on how I can improve them for faster processing. try: # conversion to ascii if utf16 data is formatted correctly input = open(filename).read().decode('UTF16')

问题 I'm trying to replace a substring in a Word file, using the following command sequence in Python. The code alone works perfectly fine - even with the exact same Word file, but when embedding it in a larger scale project structure, it throws an error at exact that spot. I'm clueless as to what causes it, as it seemingly has nothing to do with the code and seems unreproducible for me. Side note: I know what's causing the Error, it's a german 'ü' in the Word file, but it's needed and removing it
