The compiler allows the usage of national characters in variable, constant and function names.
I have discovered a contradiction of the autocompletion with this feature.

The Hungarian alphabet uses accented vowels:

If I define names like
Verb (sparrow)
V

We will look at it.

Thomas,

The distributed version of the autocompletion collects the variable names in the clauses using a negative decision.
If the character is not in the {A..Z,a..z,0..9 underscore} set then the variable name has ended.
The patching of this set is tiresome. The list would be toooooooooooo looooooong. The danger that you forget a national character is apparent.

This positive decision will collect the whole national names:
If the character is in the set of separators {space, tab, newline, comma, semicolon, colon, period, parentheses, brackets} set then the variable name has ended.

Thank you. But actually I think we can handle this : it should work in the same way as the compiler.

Thomas,

Indeed. I do not know how the complier collects the variable names but it collects them correctly. I attach the autocompletion of control names of a form defined during the automatic code generation.

We use the Windows API function IsCharAlpha.

It is available through string_native:

Thomas,
Thanky you for the mentioning of string_native library.
There are so many classes in the PFC which I have overlooked.

Normally, you should not use the _native classes directly, but it is not always that we get things mapped all the way to the "user" level.

The predicate string::hasAlpha does the same just for an entire string, i.e. it uses isCharAlpha on all the characters in the string and succeeds if they are all "alpha".
