The encoding of the GBK simplified character set uses 1 bytes and 2 bytes at the same time, when the high position is 0x00~0x7f, it is a byte, and the high position is 0x80 above with 2 bytes. When a byte is found to be larger than 0x7f, it must be a kanji (with another byte pieced together into a Chinese chara

1. Magic numbers, also known as numerical Constants
In short, there is a digital stamp, and no one knows what this means. This kind of code also causes a problem when the value of the code changes, it cannot be ensured that all relevant code is modified.
There are too many such cases in openwnn, so I will not list them one by one.
The same String constant is also a problem.
Defining constants in this case is not the only way to solve the proble
. For example, if (! Mnoinput) is not as easy to understand as if (hasinput.
There are several negative naming rules in openwnn.
Defasoftsoftkeyboard. mnoinput indicates no inputDefasoftsoftkeyboard. mdisablekeyinput indicates that keyboard input is disabled.Defasoftsoftkeyboard. mhardkeyboardhidden indicates hard keyboard hidingIsnotcomposing in openwnnjajp. onupdateselection indicates that composingtext is not selected.
However, this does not mean that the negative naming must be poor, su

Except in the following cases,Nchar,NvarcharAndNtextAndChar,VarcharAndTextUse the same:
Unicode supports a wider range of characters.
Storing Unicode characters requires more space.
NcharThe maximum size of a column is 4,000 charactersCharAndVarcharThey are 8,000 characters different from each other.
