Seems you never read it... It's defined as simple xs:string which is a "... finite-length sequence of characters that match the Char production from [XML 1.0 (Second Edition)]" whereby Char is defined as: Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */ or in other words: almost every character. > Anyway, MapServer encoding layers also doesn't seem to make > sense too... It's the only way to get a valid URL. See RFC 1738 "Uniform Resource Locators" why. > METADATA > wms_name "layer with understandable name, another layer" > > (...) > And I make a request to MapServer, what it sends to the original WMS server > looks like: > http://..../WMSServer/request=getmap&*layers=layer%20with%20understandab le%20name%2C%20another%20layer*&otherparams According to the code, the ',' from the wms_name metadata won't be encoded by mapserver. The problem with your example is probably the first space after the comma which is treated as part of the second layer name. Anyway, you can specify most of the static parts of the URL, especially the LAYERS parameter directly in the CONNECTION string. So you can try LAYER [...] CONNECTIONTYPE WMS CONNECTION "http://..../WMSServer?LAYERS=layer+with+understandable+name,another+lay er&" Note: some servers, especially the ones you deal with are a bit pitty in some details, so you should try a space both in hex encoded version %20 and the plus version. Funny things might happen when it comes to unicode characters above 0x7F. If the capabilities document is UTF-8 encoded and contains multibyte characters their URL encoding is the hexencoding of the corresponding UTF-8 bytestream (with some caveats). Using non-ASCII characters or those with a special meaning in URLs for layer names is calling for trouble. A layer's name is for machines, it's title is for humans.
