RTF export: UTF-8 to ANSI conversion?

[Markus]

Hello

I try to write RTF files using text in UTF-8 encoding. Converting the
text with utf8_decode() already fails on characters such as an
apostrophe or an endash. Of course non-Latin-1 characters would go lost.
Trying to understand the RTF spec I found that ISO-8859-1 is not
available in RTF, but only the Windows 1252 codepage which differs from
Latin-1 in some characters.

So I set the codepage to 1252 and learned that characters not contained
in this codepage should be placed as Unicode:

<quote>
For example, the text Lab[Gamma]Value (Unicode characters 0x004c,
0x0061, 0x0062, 0x0393, 0x0056, 0x0061, 0x006c, 0x0075, 0x0065) should
be represented as follows (assuming a previous \ucl):

Lab\u915Gvalue
</quote>

Now I don't understand this anymore... What does the G after the decimal
value mean? How should this \ucl be applied? ...

So these are actually my questions:
- Is there a good way to convert an UTF-8 string into CP1252, without
losing the non-CP1252 character info? (mbstring is not available on that
server)
- Can somebody point me to an easy to understand RTF tutorial?

Thanks for any hint!

You will always lose some characters wile converting utf-8 to encoding
that can handle up to 255 chars.

I haven't done anything related to RTF, but to convert UTF8 to CP-1252
you can use iconv library:

with optional //IGNORE and //TRANSLIT modifiers
