;  Converts a file containing the following to windows-1252:

;  <greetings>
;      <message>Hello, world!</message>
;      <message>¡Hola, mundo!</message>
;      <message>Bonjour, le monde!</message>
;      <message>Hallo, Welt!</message>
;      <message>Olá, mundo!</message>
;      <message>Привет, мир!</message>
;      <message>你好,世界!</message>
;      <message>こんにちは、世界!</message>
;      <message>안녕하세요, 세계!</message>
;      <message>😊🌍</message>
;  </greetings>

;  --------------------------------------------------------------------------------------------------------------------------
;  Note:
;  Windows-1252 is an 8-bit single-byte encoding. It can only encode:
;  
;      The basic ASCII set (0x00–0x7F).
;      Latin-1 Supplement (0xA0–0xFF), plus some extra printable characters (like curly quotes, €, etc.).
;      In total: 256 possible code points, covering most Western European languages but nothing outside of Latin script.

;  --------------------------------------------------------------------------------------------------------------------------
;  Characters in your XML that are representable
;  
;      Hello, world! ✅ (ASCII only)
;      ¡Hola, mundo! ✅ (inverted exclamation mark U+00A1 is in Windows-1252)
;      Bonjour, le monde! ✅
;      Hallo, Welt! ✅
;      Olá, mundo! ✅ (U+00E1 á and U+00F3 ó are in Windows-1252)

;  --------------------------------------------------------------------------------------------------------------------------
;  Characters that break conversion
;  
;      Russian / Cyrillic: Привет, мир!
;      → These are Cyrillic characters (U+041F … U+0440). Not representable in Windows-1252. Conversion would require replacement (e.g. with ? or XML character references).
;      Chinese: 你好,世界!
;      → CJK ideographs (U+4F60, U+597D, etc.). Not in Windows-1252.
;      Japanese: こんにちは、世界!
;      → Hiragana + CJK. Not in Windows-1252.
;      Korean: 안녕하세요, 세계!
;      → Hangul syllables. Not in Windows-1252.
;      Emoji: 😊🌍
;      → Unicode Supplementary Multilingual Plane (U+1F60A, U+1F30D). Windows-1252 cannot encode any emoji.
