示例1: isLowSurrogate
public static isLowSurrogate(model: ICursorSimpleModel, lineNumber: number, charOffset: number): boolean {
let lineContent = model.getLineContent(lineNumber);
if (charOffset < 0 || charOffset >= lineContent.length) {
return false;
}

let column = start.column;
let lineNumber = start.lineNumber;
if (column > model.getLineMinColumn(lineNumber)) {
if (isLowSurrogate(model.getLineContent(lineNumber).charCodeAt(column - 2))) {
// character before column is a low surrogate
column = column - 2;
} else {
column = column - 1;
}
} else if (lineNumber > 1) {
lineNumber = lineNumber - 1;
column = model.getLineMaxColumn(lineNumber);
