git checkout - How to get a copy of an older version of a file in a git repository? -

i have version of .tex file number of commits ago re-create of. have sha1 hash value commit has version of file want. not want replace current version of file. rather, want separate re-create of reflects state @ older version.

a lot of similar questions suggest using git checkout <sha1> -- file.tex, keeps giving "error: pathspec 'file.tex' did not match file(s) known git."

the file interested in existed in top-level directory of repository. in sub-directory of repository trying run command older version of file.tex in subdirectory.

is possible? how can this?

you can utilize git cat-file dump contents of file standard output , redirect desired destination:

git cat-file -p <sha1>:./file.tex > wherever.tex

the ./ necessary if in subdirectory of repository, if you're in top-level of repository may omitted. also, may not work in older versions of git, in case you'd need explicitly supply total path file relative repository's root.

git git-checkout

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
