string not recognized problem
显示 更早的评论
I'm not sure if this title is approprite but I feel this is a very weird problem
there is a string 'Cfi' in the string text_tmp.mat, if I use the command:
strfind(text_tmp,'Cfi')
the result is 6, when I assign it to a parameter, such a 'loc_CA', it still works.
loc_CA=strfind(text_tmp,'Cfi')
but, when I put the command into a .m file and run this .m file, the result becomes empty:
load text_tmp
loc_CA=strfind(text_tmp,'Cfi')
is there any mistake with my operation?
Thanks!

Exactly what is that last character? It's not a regular Western type letter. And exactly how did you save the .mat file?

Again, exactly how did you save the .mat file? What is the line of code? If you told it to save it as text, then that may be the problem. Just tell it to save the variable as-is, in the native, proprietary .mat file format that MATLAB likes - essentially the default save with no option telling it to save as text.

"It's not a regular Western type letter"
It looks like a standard f-ligature to me:
When I searched for it using an online Unicode search engine it identified it as 'LATIN SMALL LIGATURE FI' (U+FB01).

I figured it was some unicode character but by "regular", I meant it does not show up on my standard English keyboard. Most unicode characters don't. All I was able to do was to verify what Yu did, but I have no explanation for it. Do you?
