The problem is that when I had MS Office 2013 I could use letters in Excel worksheets' names like "Ó, Ő, Ű" etc. but I had an OS and software update recently at my company (from Win7 to Win10, and from MS Office 2013 to 2016), and now some character with such diacritical marks has been replaced with letters without these marks like "O, U".

For example I had a worksheet called: **Sheet1 (Összeszámolás)** in MS Office 2013

Now that worksheet is called: **Sheet1 (Osszeszámolás)** in MS Office 2016

If I use the lastly mentioned worksheet name when I'm calling a worksheet then the ones who have MS Office 2013 won't be able to operate with the excel (VBA doesn't find the actual sheet). 

Indexing with worksheet numbers doesn't work (e.g **Sheets(2).Select**) because MS Office 2013 indexes differently than version 2016. **Sheets(2).Select** selects the 2nd worksheet in MSO 2013 but in 2016 it selects the 3rd one.. 

Am I able to make excel ignore the accents so **Sheets("Osszeszamolas")** would be able to select either **Sheet1 (Összeszámolás)** and **Sheet1 (Osszeszámolás)** 

Note: I've tried to look for language options, but there ain't any options that could handle these specific accents..
