Conversion of Chinese characters and Unicode codes

During the summer vacation, I didn't go home. I stayed at school to do a text message sending project. The conversion of Chinese characters and Unicode codes made me quite awkward. At the beginning, I started to use C language, and there was always garbled code, it took a long time to get stuck. Later, I accidentally saw it on the Internet and said it could be implemented using QT ,.. Haha, I found a piece of code on the Internet and finally solved it... To share:

# Ifndef widget_h
2 # define widget_h
3 # include <qwidget>
4 class Widget: Public qwidget
5 {
6 q_object
7
8 public:
9 widgets (qwidget * parent = 0 );
10 qstring stringtounicode (qstring Str );
11 qstring unicodetostring (qstring Str );
12
13
14 };
15
16
17 # endif

# Include <qtgui/qapplication>
2 # include <qstring>
3 # include <qobject>
4 # include <qdebug>
5 # include <qtextcodec>
6 # include "Main. H"
7
8
9 Widget: widget (qwidget * parent): qwidget (parent)
10 {
11}
12
13 qstring Widget: stringtounicode (qstring Str)
14 {
15
16
17 // tr must be added to the string sent here, And qtextcodec: setcodecfortr (qtextcodec: codecforlocale () can be added to the main function ());
18
19 // example: Str = tr ("hello ");
20
21 const qchar * q;
22
23 qchar qtmp;
24
25 qstring str0, Strout;
26
27 int num;
28
29 q = Str. Unicode ();
30
31 int Len = Str. Count ();
32
33 for (INT I = 0; I <Len; I ++)
34
35 {qtmp = (qchar) * q ++;
36
37 num = qtmp. Unicode ();
38
39 if (Num & lt; 255)
40
41 Strout + = "00"; // Add "00" before an English letter or number"
42
43
44
45 str0 = str0.setnum (Num, 16); // convert to hexadecimal number
46
47
48
49 Strout + = str0;
50
51}
52
53
54
55
56
57 Return Strout;
58
59
60
61}
62
63 qstring Widget: unicodetostring (qstring Str)
64
65 {
66
67 // For example, STR = "4f60597d ";
68
69 int temp [400];
70
71. qchar [100];
72
73 qstring Strout;
74
75 bool OK;
76
77 int COUNT = Str. Count ();
78
79 int Len = count/4;
80
81 For (INT I = 0; I <count; I + = 4)
82

83 {
84
85 temp [I] = Str. mid (I, 4). toint (& OK, 16); // convert every four digits to a hexadecimal integer.
86
87 qchar [I/4] = temp [I];
88
89 qstring str0 (qchar, Len );
90
91 Strout = str0;
92
93}
94
95 return Strout;
96
97}
98
99 int main (INT argc, char * argv [])
100 {
101
102 qapplication app (argc, argv );
103
104 widget * WID = new widget;
105
106 qtextcodec: setcodecfortr (qtextcodec: codecforlocale ());
107 qstring str_c = qobject: TR ("have a good time! ");
108
109 // qstring STR = "5de54f5c61095febff01"; // Unicode code that works well
110 qstring STR = "5de54f5c61095feb00200021"; // It is also a good Unicode code
111
112 qstring str1 = wid-> unicodetostring (STR );
113 qstring str2 = wid-> stringtounicode (str_c );
114
115 qdebug () <str1;
116 qdebug () <str2;
117
118 return app.exe C ();
119
120
121}

Finally, I can go home for a good summer vacation and meet my big 3 !!! 79,1-8 50%
