bugs - Cannot import Excel (xls or xlsx) files which have non-ASCII characters in the name


It seems mma9 works fine, but with mma10 it fail to load a file name with Chinese characters. I use MacBook Pro(Retina) with OSX 10.10.2, and Mathematica 10.0.0.0. I need the file name with Chinese characters, and how can I fix it?


Here is my code:


In[309]:= Import["20150226-9999指數.xls", {"Data", -1}]



During evaluation of In[309]:= Import::fnfnd: File /Users/TWSE-data/20150226-9999指數.xls not found. >>

Out[309]= $Failed



Let me clear situation now:


.txt file format works fine, but not for .xls file with Chinese character It may be system dependent problem.


In[37]:= Import["4拷貝.txt"]

Out[37]= "this is test file"


In[38]:= Import["20150226-9999TWRI拷貝.xls"]

During evaluation of In[38]:= Import::fnfnd: File /Users/TWSE-data/20150226-9999TWRI拷貝.xls not found. >>

Out[38]= $Failed

In[39]:= Import["20150226-9999TWRI.xls"]

Out[39]= {{{92.48, 92.48, 92.48, 92.48, 0., 0.}, {92.48, 92.48, 92.48,

92.48, 0., 0.}}}

In[40]:= $Version

Out[40]= "10.0 for Mac OS X x86 (64-bit) (December 4, 2014)"

Answer



I can reproduce this problem on OS X with Mathematica 10.0.2, but with XLS and XLSX files only. Thus it's different from this bug which existed in version 10.0.0 and affected all files, and was fixed later.


I believe that this is a bug and you should report this to Wolfram Support so it can be fixed. Mathematica.SE is not a website run by Wolfram Research and reporting bugs only here won't get them fixed.




Here's a workaround that doesn't require renaming the file:



In[1]:= Import["~/Desktop/中.xlsx", "XLSX"]

During evaluation of In[1]:= Import::fnfnd: File /Users/szhorvat/Desktop/中.xlsx not found. >>

During evaluation of In[1]:= Import::fmterr: Cannot import data as XLSX format. >>

Out[1]= $Failed

In[2]:= stream = OpenRead["~/Desktop/中.xlsx"]
Out[2]= InputStream["/Users/szhorvat/Desktop/中.xlsx", 3]


In[3]:= Import[stream, "XLSX"]
Out[3]= {{{1.}, {2.}, {3.}}}

In[4]:= Close[stream]
Out[4]= "/Users/szhorvat/Desktop/中.xlsx"

You could package this up into a function for convenience.

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...

mathematical optimization - Minimizing using indices, error: Part::pkspec1: The expression cannot be used as a part specification

I want to use Minimize where the variables to minimize are indices pointing into an array. Here a MWE that hopefully shows what my problem is. vars = u@# & /@ Range[3]; cons = Flatten@ { Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; Minimize[{Total@((vec1[[#]] - vec2[[u[#]]])^2 & /@ Range[1, 3]), cons}, vars, Integers] The error I get: Part::pkspec1: The expression u[1] cannot be used as a part specification. >> Answer Ok, it seems that one can get around Mathematica trying to evaluate vec2[[u[1]]] too early by using the function Indexed[vec2,u[1]] . The working MWE would then look like the following: vars = u@# & /@ Range[3]; cons = Flatten@{ Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; NMinimize[ {Total@((vec1[[#]] - Indexed[vec2, u[#]])^2 & /@ R...
