Hello, the problem is only linux.

The following source code uses UTF8 without BOM,
http://www.conoce3000.com/Ejemplo01.pp
the compiler compiles ok and the program displays the message in Unicode UTF8 ok

The following source code uses UTF8 with BOM
http://www.conoce3000.com/Ejemplo02.pp
the compiler compiles ok and the program displays the message in Unicode UTF8 with question marks.

How can I tell the compiler to ignore the BOM?

Thanks

You cannot. Your first program will however only work on terminals that are configured to accept UTF-8 output. The correct way is to a) use the second program (or add {$codepage utf8} at the top of the first one)
b) add "uses cwstring;" so that a widestring manager is available, which will convert the strings (which are parsed into widestrings) to the current session's code page.

Thanks, that works. but,
What is a widestring manager?

d) IBM 850
e) Unicode-UTF8

if your answer is (a), then :
What disadvantages does use the Unicode-UTF8?

every one. whatever you like. whatever fits best.

English:
Most commonly, Linux and Windows, both 32 bits.
I want to use Unicode-UTF8 with linux and want to use Win-1252 with Windows. My question is: Is my decision right?

Spanish :
Lo más común, linux y windows, ambos 32 bits.
Deseo usar Unicode-UTF8 con linux y deseo usar Win-1252 con Windows. Mi pregunta es : ¿Es adecuada mi decisión?
