TM Character over XML

What am I missing?

[dataguy]

I serve an XML feed to a number of web sites and this morning a webmaster brought to my attention the fact that special characters such as the trademark (™) character comes out as a question mark through the feed.

I can see the TM character OK when I view the database fields directly, but not in the feed. I'm using encoding="ISO-8859-1", does that have something to do with it?

Probably.

FWICS TM is entity ™ which puts it outside of ISO-8859-1

Its likely that the locale of your database is UTF-8 and therefore so should your feed.

Depending on how you are using the XML, you could also do a superscript of the letters TM. There are cases where this is preferable (for example, if you do several languages and one of the languages doesn't use the word "Trademark").

Apparently ISO-8859-1 does not handle the trademark symbol, and I am stuck with using ISO-8859-1. I've had to create some encodeing of my own, which seems to be working fine. I'm replacing the TM symbol with '[TM}', sending it as ISO-8859-1, and then changing it back to the symbol on the client end.

Thanks for your help!
