Hello again.
In a combobox, some items are Greek letters.
By clicking "OK", a chart is generated from data in many sheets through a ".find()" which looks for the contents of the combobox (which may be Greek characters, such as alpha, beta, etc.) and takes the values of cells to construct the chart.

However, I must write the word to be sought not only within ".find ()" but as a case of "Select Case ". So how to proceed?
