Leaflet vs ArcGIS JS / FeatureLayer

By -
I'd been deciding ESRI-Leaflet or ArcGIS JS for a small project. Some findings for our references:

When using FeatureLayer for plenty amount of data (e.g. vast amount of points), ArcGIS JS performs better than Leaflet. So even the file size of Leaflet is far smaller than ArcGIS JS, I still have to choose the larger one.

Hope Leaflet FeatureLayer performance can boost up in future.

Java encoding : UTF-8, Big5, x-MS950-HKSCS

Suppose you got a file in Big5 containing some HKSCS characters (e.g. 深水埗, 赤鱲角, etc). When your environment (Ref: Charset.defaultCharset( ) ) is either UTF-8 / Big5, you will never get the things work. The proper encoding should be "x-MS950-HKSCS" This situation happens when I'm try the same pieces of code in Java console / Eclipse console and JSP @ Tomcat. While JSP works fine, but sucks in console mode. Finally I found the JSP is actually using encoding "x-MS950-HKSCS". To set environment charset in Eclipse: Right click on the file that you are going to execute (e.g. Testing.java), then "Properties" → "Run/Debug Settings" → "Common" → "Encoding". Type "x-MS950-HKSCS" in the field. What a pity!
