I don't know why I'm responding this late in the thread, OP probably isn't going to read this, but I work with kids for a living and actually have run into this issue on multiple occasions so whatever I'll say it anyway. Weird or unique names tend to be a minefield, they can turn out well, or blow up in your face and cause your kid a lot of unnecessary grief. Of the kids I've worked with over the years that have eventually gotten old enough and changed their legal names, they were all kids with unique or quirky names that their parents thought was cute or awesome when they were born.
Especially names of fictional characters that stand out, I knew one kid who was saddled with the name Skywalker, yes, I don't know exactly why his parents gave him the last name of a Star Wars character as his first name, but he claims that's where they got the idea from because they thought it sounded cool, and he pretty much refused to answer to anything except Walker. When he turned 18, the first thing he did that day after school was file to have his name changed to just Walker. I've never encountered that with people with more widespread names, so be prepared, because your girl may very well end up loathing that name and counting down the days until she can change it herself, kids sometimes don't like their given names, but it's always the more unique and quirky ones that seem to ignite that all-consuming passion to change it as soon as possible. Still, it's a crap-shoot, the more unique names tend to inspire more hatred from those saddled with them, but I've also met kids that like them, so who knows, maybe she'll love it, and maybe she will have her name change paperwork filled out and ready to mail in years in advance.
Another issue people bring up is jobs, and as much as it sucks, there are definitely biases in Human resources departments when it comes to hiring people with out there names. If you have two equal resumes, except one person is named Arthur Mason, and the other one is name Superman McGee, I can guarantee the guy with the normal name is going to get the callback almost every time. Dunno how much you'll have to worry about this though, Tali'zorah sounds more foreign than just outright wacky, but then again, depending on where you live, a foreign sounding name can get you passed over for jobs as well. That's not really, your, or your kids fault, but it's a risk you take with names like that, just be aware of the possibility and a smart person should be able to mitigate the problems.
Although, I do have to question, why bother to actually put her name down as Tali'zorah, if you're just going to call her Tali all the time, seems like a pointless complication to me. The only thing it accomplishes is making official paperwork more of a pain in the ass, and the apostrophe is going to cause a screw-up by the government bureaucracy somewhere down the line. Last time I remember a kid with an apostrophe in her name ended up spending hundreds in court fees, after a computer system fucked up her name because it couldn't process apostrophes in the name field correctly. Not really your fault, but be aware that somewhere down the line that apostrophe is likely going to fuck something up, and you'll need to be extra careful in any paperwork you or she fills out that will require her full legal name. I can't begin to tell you the number of times someone with a name with odd punctuation in it has resulted in people not getting paperwork properly sent, or important calls and notices not going through properly.
It probably won't be some terrible burden on your kid, and if she ends up liking the name, it will certainly be an uncommon one, (not unique, I'm willing to bet there are already a couple Tali'zorahs out there) so yeah, good luck, just make sure you fill out her full legal name properly or you're going to be giving some poor government bureaucrat a major headache down the line. Also, don't take it personally if she ends up fucking hating her name, it's a risk with this type of thing, but changing your name isn't too hard in the U.S., kind of a pain in the ass, but hey, that's what nicknames are for, and there are a lot worse things you can shorten a name to than just Tali.
