Stuff like that doesn't bother me at all, but I bumped into quite a few immigrants who had strong preferences one way or the other.
When someone says luke, yeah I'll get it and I definitely don't mind, but IPA /lyk/ or French Luc is what my name is. Apparently the /y/ sound just doesn't exist in most languages I interact with and that makes it impossible for virtually any non-French/Dutch person to pronounce it properly. I don't fault them, I don't mind, but I appreciate if someone makes an effort (even if it's wrong, it's only about trying) to call me by my name rather than by a translation thereof.
(Edit: wtf, don't trust tools like http://ipa-reader.xyz that is near the top of search results. The default american voice pronounces /y/ like the "o" in "who". What's the point of IPA reader if you're going to pronounce an A like a B when your language doesn't have the A sound?! Accent is fine but don't change the sound to a different IPA character altogether... For the symbols /lyk/, I've tested all voices: Dutch, French (+Canadian), Icelandic, German, Norwegian, Turkish, and Swedish are correct, whereas English, Italian, Japanese, and Portuguese incorrectly read the IPA. Some others are glitchy or mixed results between male/female voices.)
Btw, this sound also exists in German and is spelled “y”. If you meet a German and want them to say your name in your preferred way, tell them to imagine it’s spelled “Lyk”.
Lyk is an interesting option I should try with germans. It makes the vowel sound a bit too 'short' but it's very close indeed. Let's see what results that gets compared to Lüc :)
I'm guessing the goal is to reproduce an accent, but if the natural language doesn't have the IPA in its phonology, then it's going to be mapped to the nearest representation. English doesn't distinguish between /y/ and /u/, so a native English speaker being asked to reproduce a /y/ sound (especially in running speech where you're not thinking about how to pronounce the sound in particular) is likely to end up with something near /u/ anyways.
Giving you flat-out the wrong sound (not an accented rendition) should not be default behavior. There could be an option for rendering "how would an american approximate/recreate this sound after I sounded it out to them", but that's a different tool and not an IPA-to-sound converter.

The consonant at the end of my name makes it impossible for many people to pronounce it correctly. You would have a similar problem; a Mandarin speaker would have no difficulty producing /ly/, but in the best case your full name would come out in two syllables as /ly.kɤ/.
If it's any consolation, the original form of the name had /u/, and the French /y/ is a later historical development internal to French. ;D
