I confirm this, lou_checktable drops 16 errors the ru-ru-comp8 table between 252th and 267th lines. Both 16 errors following the error message: Exactly one Unicode character and at least one cell are required.
For example the 252th line containing following rule: space \x02219 238 BULLET OPERATOR Clear seeing the unicode character in the rule are containing five digits. This table are broken the 2.5.1 prewious Liblouis version too.I attached a patch with perhaps solve this issue, but a russian table user please test the table this affected characters before commit. John, need releasing a new bugfix release if this patch are good? Peter, you possible testing this table after applied the attached patch? I simple cutted the first 0 digit this affected unicode characters. I verifyed for example the \x02219 character in Gedit, the resulted unicode character is unicode 2219, so I think this fix will be good. Lou_checktable not will be drop errors the new modified table if this patch are committed.
I have got a question before I making the final patch if any changes are needed: not need renaming this table from ru-ru-comp8 to ru-ru-comp8.ctb filename? For example Orca founding only with ru and ru-ru-g1 table, real table filenames is ru.ctb and ru-ru-g1.utb in the Liblouis tables directory.
