Licensing question related to UTF-8 code in GLib

["Nikolai Weibull" <now bitwi se>]

Hi!

I have written a library [1] that is currently under consideration for
(at least partial) inclusion in Ruby 2.0 [2].  I used GLib as a
reference implementation while writing this library and I am thus
wondering exactly how licensing works in this situation.

GLib is released under the LGPL and Ruby is released under its own
license [3].  According to the Wikipedia entry [4], the FSF has
claimed that: "This is a Free Software license, compatible with the
GPL via an explicit dual-licensing clause." [5]

I thus wonder if there is any issue in including code based on [6]
code in GLib in a project licensed under the Ruby license.

Thanks!
