Simple tools for text having a single-byte encoding

The code is low-level, and examines byte-values directly.

The various classes are mostly independent of each other:

• examine a file's bytes
• stats for the bytes appearing in a file
• find-and-replace a given byte
• change straight-quotes (not pretty) to curly-quotes (pretty) (using windows-1252)

I tried to write a tool to inspect the bytes on the clipboard, but apparently OS's don't allow that.

Example output of Histogram.java

The Histogram.java class outputs a summary of the byte-values that occur in a given text. It's a good place to start when analyzing text.

The output to stdout looks like this:

00(0):0
01(1):0
02(2):0
03(3):0
04(4):0
05(5):0

0E(14):0
0F(15):0

Notepad++

Its Encoding menu is split into two parts:

• render these bytes assuming encoding X
• attempt to convert these bytes to encoding Y

The word ANSI may not mean what you think it means:

Be careful of its default behavior:
