Notepadqq: Text editor
Meld: Text files diff and merge (No context menu to select 2 files and open the application)

KDiff3: Text files diff and merge (Context menu to select 2 files and open the application. Also select files one after the other)

## Java Unicode Notes.txt
U+FFFF (Uniicode repesentation) is same as 0xFFFF (Hexa decimal)

To convert "U+FFFF" to code point
int codepoint=Integer.parseInt(str.substring(2), 16);

Basic Multilingual Pane (BMP) = U+00000 (    0)   to U+FFFF   (  65535) (1111111111111111 (16 1s) in Binary)
Supplementary chars           = U+10000 (65536)   to U+10FFFF (1114111)
All unicode characters        = U+00000 (    0)   to U+10FFFF (1114111)

An unicode character in Java represented by two UTF-16 characters
