The Unicode glyphs that you have queried (U+015E, U+015F, U+0162, U+0163) should have cedilla accents as defined in the Unicode Standard. In Ubuntu Beta U+015E, U+015F do have cedillas but U+0162, U+0163 have commas. We will change this.
Also according to the Unicode Standard, Romanian's prefer commas to cedillas and define U+0218, U+0219, U+021A, U+021B as being for Romanian. To enforce this we include a local table that replaces U+015E, U+015F, U+0162, U+0163 with U+0218, U+0219, U+021A, U+021B in Romanian and Moldavian, but this may not work in all applications.
Mihai, Sorry for the confusion regarding R's.
