This file contains invisible Unicode characters

This file contains invisible Unicode characters that are indistinguishable to humans but may be processed differently by a computer. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

Changes in 2.31:
+* Tools which display names or strings (readelf, strings, nm, objdump)
+ have a new command line option which controls how unicode characters are
+ handled. By default they are treated as normal for the tool. Using
+ --unicode=locale will display them according to the current locale.
+ Using --unicode=hex will display them as hex byte values, whilst
+ --unicode=escape will display them as escape sequences. In addition
+ using --unicode=highlight will display them as unicode escape sequences
+ highlighted in red (if supported by the output device).

* Add support for disassembling netronome Flow Processor (NFP) firmware files.
* The AArch64 port now supports showing disassembly notes which are emitted

+Controls the display of non-ASCII characters in identifier names.
+The default (\fB\-\-unicode=locale\fR or \fB\-\-unicode=default\fR) is
+to treat them as multibyte characters and display them in the current
+locale. All other versions of this option treat the bytes as \s-1UTF\-8\s0
+encoded values and attempt to interpret them. If they cannot be
+interpreted or if the \fB\-\-unicode=invalid\fR option is used then
+they are displayed as a sequence of hex bytes, encloses in curly
+parethesis characters.
+.Sp
+Using the \fB\-\-unicode=escape\fR option will display the characters
+as as unicode escape sequences (\fI\euxxxx\fR). Using the
+\&\fB\-\-unicode=hex\fR will display the characters as hex byte
+sequences enclosed between angle brackets.
+.Sp
+Using the \fB\-\-unicode=highlight\fR will display the characters as
+unicode escape sequences but it will also highlighted them in red,
+assuming that colouring is supported by the output device. The
+colouring is intended to draw attention to the presence of unicode
+sequences when they might not be expected.
