Hello I am brand new to programming with Lisp and I have been following a tutorial on YouTube.(https://www.youtube.com/watch?time_continue=56&v=ymSq4wHrqyU&feature=emb_logo)
I am using clisp. When I type clisp in the terminal I can code with lisp but I want to be able to use TextEdit to save my file and I have created a file in TextEdit with the extension ".lisp"
However, when I try to execute it from the terminal I am met with this message:
Renes-MBP-2:~ renegutierrez$ clisp test.lisp
*** - EVAL: variable |{rTF1aNSIaNSICPG1252cOCOARTF2511| has no value
The only thing in my file is:
(print "Hello World")
Any help would be much appreciated thank you so much.
With the little information you give, it's difficult to diagnose, but I will give it a shot.
TextEdit uses a BOM (byte-order mark), that is a few invisible bytes at the beginning of the file which tells the editor how to decode the data in it. However, CLISP might get confused with these bytes and return an error.
The solution in this case would be to tell TextEdit to save only text. To do that, in TextEdit go to TextEdit -> Preferences and select Format Plain Text.
Save your file again with these new settings and see if now it loads in CLISP.
With the initial default settings, TextEdit writes RTF (Rich Text Format) by default. When you look at the file through the Terminal, you'll notice that your file starts with
{\rtf1\ansi\ansicpg1252\cocoartf2511
Make sure to convert the file to plain text, through the Format menu.

I'm not used to c or c++ or AHK. My problem is the following:
There exists a tool called "TI Helper", which is composed of 1 EXE and several text files. This EXE enables you to press "CTR+SPACE" in TM1 application, which will popup a (right-click kind of menu) based on the text files...
I opened the EXE with notepad and we can see the code...
Can i simply re-use or modify this code? WHat should i keep in mind?
This has nothing to do with C, C++ or assembly and you have neither decompiled, nor can you recompile the executable.
TIHelper is an open source AHK (autohotkey scripting language) file. As a script file, it is not compiled into unreadable machine gibberish, but instead interpreted in it's human readable form.
You are free to make changes to that AHK file and run with those changes.

First of all - will any exe file modifications violate or comply software licensing terms?
If it is allowed, you should know the format of exe file, better if assembler language too.
Generally, modifying data segment in exe file (e.g. 13 characters "File created" to "Result is OK" - watching that total number of exe file bytes will not change) could eventually result only in changes in displayed text.
Modifying binary code (code segment of exe file) requires understading what "mov ax,60" is, what could it cause and could give expected result ONLY if machine (assembler) code is fully understood.
I'd like to use Unicode characters in comments in a MATLAB source file. This seems to work when I write the text; however, if I close the file and reload it, "unusual" characters have been turned into question marks. I guess MATLAB is saving the file as ASCII.
Is there any way to tell MATLAB to use UTF-8 instead?
According to http://www.mathworks.de/matlabcentral/newsreader/view_thread/238995
feature('DefaultCharacterSet', 'UTF8')
will change the encoding to UTF-8. You can put the line above in your startup.m file.
How the MATLAB Process Uses Locale Settings shows how to set the encoding for different platforms. Use
feature('DefaultCharacterSet')
You can read more about this undocumented function here. See also this Matlab Central thread for other options.
Mac OSX only!
As I found solution which worked in my case I want to share it.
Mathworks advises here to use slCharacterEncoding(encoding) in order to change the encoding as desired, but for the OSX this does not solve the issue exactly as the feature('DefaultCharacterSet') in accepted answer does not do it. What helped me to get the UTF-8 encoding set for opening and saving .m files was the following link on MATLAB answers:
https://www.mathworks.com/matlabcentral/answers/12422-macosx-encoding-problem
Matlab seems to ignore any value set in slCharacterEncoding(encoding) or feature('DefaultCharacterSet') but uses region set in System Preferences -> Language & Region. After checking which region is selected in our case then it is possible to define the actual encoding in the hidden configuration file in
$matlabroot/bin/lcdata.xml
This directory can be opened by getting to the Applications and after right click on Matlab by selecting Show Package Contents as on screenshot (here in German)
For example for German default ISO-8859-1 it is possible to adjust it by changing the respective line in the file lcdata.xml:
<locale name="de_DE" encoding="ISO-8859-1" xpg_name="de_DE.ISO8859-1">
to:
<locale name="de_DE" encoding="UTF-8" xpg_name="de_DE.UTF-8">
If the region which is selected is not present in the lcdata.xml file this will not work.
Hope this helps!
The solution provided here worked for me on Windows with R2018a.
In case link doesn't work: the idea is to use file matlabroot/bin/lcdata.xml to configure an alias for encoding name (some explanation can be found in this very file in the comments):
<codeset>
<encoding name="UTF-8">
<encoding_alias name="windows-1252" />
</encoding>
</codeset>
You would use your own value instead of windows-1252, currently used encoding can be obtained by running feature('locale').
Although, if you use Unicode characters in help comments, the help browser does not recognize them, as well as console window output.
For Mac OS users, Jendker's solution really helps!!! Thanks a lot first.
Recap here.
Check the default language in Matlab by typing in the command window getenv('LANG'). Mine returned en_US.ISO8859-1.
In the Application directory find Matlab, show its package contents. Go to bin, open lcdata.xml as an administrator, locate the corresponding xpg_name, in my case en_US.ISO8859-1. Change encoding in the same line to UTF-8. Save it.
Restart Matlab, and it's all done!
I could not find this answer in the man or info pages, nor with a search here or on Google. I have a file which is, in essence, a text file, but it somehow got screwed up upon saving. (I think there are a few strange bytes at the front of the file accidentally.)
I am able to open the file, and it makes sense, using head or cat, but not using any sort of editor.
In the end, all I wish to do is open the file in emacs, delete the "messy" characters, and save it once cleaned up. The file, however, is huge, so I need something powerful like emacs to be able to open it.
Otherwise, I suppose I can try to create a script to read this in line by line, forcing the script to read it in text format, then write it. But I wanted something quick, since I won't be doing this over & over.
Thanks!

perl -i.bk -pe 's/[^[:ascii:]]//g;' file
Found this perl one liner here: http://www.perlmonks.org/?node_id=619792
Try M-xfind-file-literally in Emacs.
You could edit the file using hexl-mode, which lets you edit the file in hexadecimal. That would let you see precisely what those offending characters are, and remove them.
It sounds like you either got a different line ending in the file (eg: carriage returns on a *nix system) or it got saved in an unexpected encoding.
You could use strings to grab "printable characters in file". You might have to play with the --encoding though I have only ever used it to grab ascii strings from executable files.

My Localizable.strings file has somehow been corrupted and I don't know how to restore it.
If I open it as a Plain Text File it starts with weird characters that I can't copy here.
If I leave the file be the app builds. If I make any changes either the values aren't interpreted properly or I get an error at compile time.
Localizable.strings: Conversion of string failed. The string is empty.
Command /Developer/Library/Xcode/Plug-ins/CoreBuildTasks.xcplugin/Contents/Resources/copystrings failed with exit code 1
I suspect this is an encoding problem but I don't know how it happened (maybe SVN is to blame?) nor how to solve it. Any tips will be much more appreciated.
I have issues with the same file that sound very similar to your own. What happens for me is that Xcode doesn't know the correct file formating. I often get this when rearranging the project and I remove and re-add this file to the Xcode project. When I re-add the file, its encoding gets set to something like Western Roman which can't seem to render anything other than ASCII.
Here's what I do to fix the problem:
In Xcode select the Localizable.stings file in the Groups&Files panel.
Do a Get Info on that file.
On the info panel select the General tab.
In that tab go to the File Encoding and change its value.
The last step is where the trick lies as you now have to guess the right encoding. I find that for most European languages that "Unicode (UTF-8)" works. And for Asian languages I find that "Unicode (UTF-16/32)" are the ones to try.
I just had that error because I forgot a semicolon. Took me a while to figure it out. Seems like a really ambiguous compiler error but the fix was simple.
Make sure in File-Get Info, that UTF-16 is selected. If it's set to none or UTF-8 as encoding then you need to change it. If your characters have spaces between them then you choose to "re-interpret" the file as UTF-16. If there are weird characters in the file, then you need to remove them.
Execpt the UTF-8 problem, sometimes you still have to check the content in case if there are some syntax problems.
Use the following Regular Expression to verify your text line by line, if there's any line not matched, there must be a problem.
"(.+?)"="(.+?)";
You can use the plutil command line tool. Without options or with the -lint option, it checks the syntax of the file given as argument. It will tell you more precisely where the error is.
This happens to me when there is a missing quote or something not right with the file. MOst commonly, since my language files are done by another team member, he tends to forget a quote or something. Usually XCode shows an error on that line, sometimes it does'nt and just throws "Corrupted data" error.
Double check if all your strings are properly closed in quotes
Open the file in Xcode.
Right click it in Project Navigator.
Select Open as -> ASCII Property List
