A right way to query password from a console in JavaScript

import * as readline from 'node:readline/promises';
import { stdin as input, stdout as output } from 'node:process';
import { Writable } from 'node:stream';

var mutableStdout = new Writable({
  write: function(chunk, encoding, callback) {
    if (!this.muted)
      output.write(chunk, encoding);
    callback();
  }
});

mutableStdout.muted = false;

var rl = readline.createInterface({
  input: input,
  output: mutableStdout,
  terminal: true
});

Conversion of S75 charts to GeoJSON with GDAL org2org utility.

The original S57 map consists of the following layers:

ogrinfo E:\temp\ENC_ROOT\US4CA11M\US4CA11M.000
INFO: Open of `E:\temp\ENC_ROOT\US4CA11M\US4CA11M.000'
      using driver `S57' successful.
1: DSID (None)
2: Point (Point)
3: Line (Line String)
4: Area (Polygon)
5: Meta (None)

So I was able to convert each layer separately one by one without errors:

ogr2ogr -f GeoJSON US1HA02M-Area.json E:\temp\ENC_ROOT\US1HA02M\US1HA02M.000 Area -lco RFC7946=YES -skipfailures
ogr2ogr -f GeoJSON US1HA02M-Point.json E:\temp\ENC_ROOT\US1HA02M\US1HA02M.000 Point -lco RFC7946=YES -skipfailures
ogr2ogr -f GeoJSON US1HA02M-Line.json E:\temp\ENC_ROOT\US1HA02M\US1HA02M.000 Line -lco RFC7946=YES -skipfailures
ogr2ogr -f GeoJSON US1HA02M-DSID.json E:\temp\ENC_ROOT\US1HA02M\US1HA02M.000 DSID -lco RFC7946=YES -skipfailures
Warning 1: No SRS set on layer. Assuming it is long/lat on WGS84 ellipsoid
ogr2ogr -f GeoJSON US1HA02M-Meta.json E:\temp\ENC_ROOT\US1HA02M\US1HA02M.000 Meta -lco RFC7946=YES -skipfailures
Warning 1: No SRS set on layer. Assuming it is long/lat on WGS84 ellipsoid
