Excerpt from this
The use of words and names like “Shmuel,” “Yeshaya,” and “Daniel” are
permitted, even though two of their letters represent Hashem’s name,
since the intended use is for a person’s name, not Hashem’s name. The
word “Bethel” can be written, as well as Beth-El in two words. Since
it is the name of a city, it does not matter how it is spelled.
See footnote (5) there. It is not linked, and they include a somewhat blurry photocopy, so I couldn't quite decipher what it says. Others are welcome to edit my answer to include it.
Note: The article is in English, so they transliterated the names. My understanding of the above quote is that they are saying that it's permissible to write the whole name in Hebrew letters without truncating or separating the letters, b/c it's not considered shaimos.
Related - There is no "Shaimos" involved in saying the name as is. My Rav relayed a story that on a date, the boy asks the girl her name, and she answers, "Bat-kah". He responds, "Nice to meet you. My name is "Kelikahu" ". It is ridiculous, no?
