/optioncompare
Specifies how string comparisons are made.
/optioncompare:{binary | text}
You can specify /optioncompare in one of two forms: /optioncompare:binary to use binary string comparisons, and /optioncompare:text to use text string comparisons. By default, the compiler uses /optioncompare:binary.
In Microsoft Windows, the code page being used determines the binary sort order. A typical binary sort order is as follows:
A < B < E < Z < a < b < e < z < À < Ê < Ø < à < ê < ø
Text-based string comparisons are based on a case-insensitive text sort order determined by your system's locale. A typical text sort order is as follows:
(A = a) < (À = à) < (B=b) < (E=e) < (Ê = ê) < (Z=z) < (Ø = ø)
