My $stylevar[languagecode] was set for a long time to the string 'heb'. I have now changed it to 'he-IL', and if i display the variable on my forums, the output is 'he-IL'. However, when i view the source on the RSS feeds (extrenal.php?type=RSS2), there is the word 'heb' between the <language></language> instead of 'he-IL'.

How can it be??
