UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-8: ordinal not in range(128)

[Radek Bartoň]

It seems you have international or other non-ascii character in some component name? Which one is it please?

[raa]

Yes, I have two components, and both are named in Russian. But I did not expect this can couse a problem. Why does this error happens? And how to fix it?

Thanks

[raa]

Excuse me please for my English :-)

Could you please explain? Do you mean a component as a ticket property or as some trac plugin?

I mean I have to predefined values for the component field of the tickets, but I do not have any non-ascii characters in file names and so on.

[raa]

_tWo_ predefined values (to => two). With russian characters. Sorry again :-)

[Radek Bartoň]

Yes, I mean the component as a ticket property. The reason is that there is no ID of component in database schema and they are identified by their name. This name is given to <input value="<component_name>"/> tag and that causes the problem. I'll search how is this solved in Trac internals or I'll introduce iteration over registered components to get their virtual ID and use it. But you must wait until I'll have more time for this.

[raa]

ok, I will wait. Thank you very much!

[Radek Bartoň]

Actually this is not problem in the plugin but the Genshi but I've added workaround for this in r4278 until it will be fixed.
