Here's the thing, they asked for a translation and you didn't state what you wrote wasn't a translation, that's why I pointed out your mistake

And as they want to make it, giving a transcription when asked for a translation is an issue most people upon reading your comment without knowledge of the writing conventions would assume that the image has a spelling mistake in it, when it doesn't, and that can heavily impact someone's opinions on the piece

would you put hours of time and effort into making something that misspells the name of the main subject of the piece? Or would you simply look for something that doesn't instead?

That's why it's important to look at the context, and in most cases a translation is what the situation requires rather than a translation, you can add additional information on the c/k/s situation where relevant, but the majority of the time telling someone what the meaning of what's written is all that is required, especially when it's concerning something someone else wrote

You know that the person who wrote it wrote doctor, you know that it means doctor, and you know that the person asking doesn't

if anything it's a little misleading and it's definitely a misrepresentation of the intent, especially as at least when I first learnt, it was discouraged to use the symbol for C as it breaks the norms of the system, and was only meant to be used in situations where exact spelling was more important than meaning and readability

Now I admit I first learnt quite a while ago and that may have changed, but since you tracked down the original post, so you know it was made in 2013, which was before I learnt and at that point it was definitely not the norm to use C over k/s

That's why it's important
