Is there any clear answer to allowing a small "c" for scottish names on napetapes?

IT's like trying to get the period that is in St.Cyr put in documents. I had a pissing contest at the reception center at FLW as a trainee because the lady who made name tapes refused to put the period in my name. Told me names don't have periods , told her the family probably knew how to spell our name. So I ended being called alphabet all through training because STCYR is a lot different than ST.Cyr.

Technically according to AR 670-1 , para 21-25, (b) page 210 us folks with non-standard common names like smith, jones, or johnson are S-O-L and doomed to standardization. Periods, umlaut's, shuays and unfortunately small case c's all would count as either punctuation, symbols or special characters ( and yes my name tapes have the period and every Mc I have ever known outside of basic training has the lower case c) but alas we are all in technical violation of the reg to include the good general pictured ......

b. Insignia, nametape.
(1) Description. For the combat utility uniforms and ECWCS, the nametape insignia is 5 inches in length with a
hook-and-loop-faced pad. The nametape will be in black block letters. The nametape is worn above the wearer’s right
breast pocket above chest pocket flap. The background of the nametape insignia is camouflage pattern. The letters are
3/4 inch high and 1/2 inch wide. No punctuation, symbols, or special characters are authorized on the nametape. (Last
names consisting of 11 letters or more are constructed using Franklin gothic extra-condensed print (48 point), 1/2 inch
high.)

Yes, there is a clear answer:
DA PAM 670-1, sec 9–24 Insignia, distinguishing, U.S. Army tape, nametape, and nameplate:
The letters are 3/4 inch high and 1/2 inch wide.
