Java/JS中的字符编码问题，在字段中带有“é"字符 [英] Character encoding issue in Java/JS with the 'é' character in a field
本文介绍了Java/JS中的字符编码问题，在字段中带有“é"字符的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
数据库(Postgresql)有一个表，该表的列名为streetaddress1(varchar(50))，其中条目为Amelié"
The database (Postgresql) has a table with a column called streetaddress1 (varchar(50)) in which the entry is 'Amelié'
UI(React/JS):
The UI (React/JS) :
var streetAddress1 = event.target[1].value;
if (valProductDescription && valModelNumber && valAssemblyNumber && valName) {
url = url + "&streetAddress=" + streetAddress1 + " " + streetAddress2;
<div>
<Modal
isOpen={openCfcOverlay}
style={customStyles}
contentLabel="modal"
<div>
<Input
errorMessage='Please enter a valid Street Address'
error={cfcDeclaration.companyAddress1Error}
title="Street Address"
type="text"
name="Street Address"
value={typeof selectedCompany == 'undefined' ? "" : selectedCompany.streetAddress1}
disabled='edit'
/>
然后在index.template.html文件中，我都尝试了
Then in the index.template.html file, I tried both
<!DOCTYPE html>
<html lang="en">
<head>
<title>Home</title>
<meta charset="utf-8">
和
<!DOCTYPE html>
<html lang="en">
<head>
<title>Home</title>
<meta charset="utf-16">
在后端(JAVA):
public CompanyRequest(JSONObject jsonObject)
this.streetAddress1 = (String) jsonObject.get("streetAddress1");
this.streetAddress2 = (String) jsonObject.get("streetAddress2");
此街道地址"字段将出现在允许pdf下载的弹出窗口中.在这里，名称Amelié"将显示为
This 'Street Address' field will appear in a pop-up that allows a pdf download. In here, the name 'Amelié' will appear as
public void generatePdf(String filePath, List<CfcRequest> cfcRequestList, String companyName, String streetAddress) throws IOException {
Document document = new Document(PageSize.A4, 36, 36, 36, 72);
try {
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(filePath));
document.open();
if (image != null) {
Image img = Image.getInstance(image, null);
img.setAbsolutePosition(36f, 775f);
img.scaleToFit(150, 40);
document.add(img);
}
String modifiedRegionAddress = "";
String country = "";
boolean zipcodeAdded = false;
String[] address = regionAddress.split(" ");
for (int i = 0; i < address.length; i ++) {

try {
Integer.parseInt(address[i]);
zipcodeAdded = true;

modifiedRegionAddress += address[i] + " ";

}
}
Paragraph header = new Paragraph("PDF Download", headerFont);
header.setAlignment(Element.ALIGN_CENTER);
header.setSpacingAfter(20);
document.add(header);
// Date and additional stuff
DateFormat df = new SimpleDateFormat("MM/dd/yy");

basicInfoTable.addCell(regionAddressCell);
basicInfoTable.addCell(emptyCell);
basicInfoTable.addCell(countryAddressCell);
basicInfoTable.addCell(emptyCell);
document.add(bodyTop);
document.add(reachTable);
document.add(bodyBottom);
final int FIRST_ROW = 0;
final int LAST_ROW = -1;
//Table must have absolute width set.
if (basicInfoTable.getTotalWidth() == 0)
basicInfoTable.setTotalWidth((document.right() - document.left()) * basicInfoTable.getWidthPercentage() / 100f);
basicInfoTable.writeSelectedRows(FIRST_ROW, LAST_ROW, document.left(), document.bottom() + basicInfoTable.getTotalHeight(), writer.getDirectContent());
document.close();
writer.close();
} catch (DocumentException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
这是utf-8/utf-16问题吗?为什么é"字符在最后一张图片的字段中显示不正确?我该如何解决?是后端更改还是UI更改?
Is this a utf-8/utf-16 problem? Why does the "é" character show up incorrectly in the field from the last picture? How do I fix this? and is it a back-end change or a UI change ?
推荐答案
PostgreSQL中模板数据库的默认编码设置为SQL_ASCII.在检索该信息之前，已将其更改为utf8吗?
The default encoding of the template databases in PostgreSQL is set to SQL_ASCII.Before retrieving that information did you change it to utf8 ?
